If the area of a circle is 58 square feet, find the circumference

Mathematics

Blizzard [7]3 years ago

Answer:

C≈27 feet

Step-by-step explanation:

A=πr²

A/π=r²

√A/π =r or –√A/π=r (refused)

then r =√(A/π) =√(58/π) =4.297829403 feet

C=2πr=2π(4.297829403)=27.00405856≈27 feet

<u>Answer:</u>

Circumference of required circle = 27.0021 feet.

<u>Solution:</u>

Given that area of circle = 58 square feet

We need to find the circumference

Circumference of circle = 2\pi r where r is radius.

We don’t have radius in given information but we do have area of circle.

So first need to calculate radius of a circle from given area.

Area of circle = \pi r^{2}

where “r” is radius of circle.

58=\pi r^{2}

r^2= (58 \times 7)/22=18.4545

So we get

r = square root of 18.4545 = 4.2958 feet

Circumference of circle = 2 \mathrm{\pi r}

= 2 (\frac{22}{7}) (4.2958) = 27.0021 feet.

Hence circumference of required circle = 27.0021 feet.

On a snowy day 85% of the students of Wilson high school were present. If 572 of the students were present, how many students we
r-ruslan [8.4K]

Answer:

673

Step-by-step explanation:

okay so uh this is my way and the answer works so like yea teachers dont show like this but ii figured this works

okay so

85/100 = 572/?

so if you divide 85 by 85 its gonna equal 1 and 1 times 100 is gonna be 100

useing the same concept, it should be the same with 572 , but instead of divideing by 572, divide by 85.

basically 572/85

okay now thats gonna give you 6.72941176471 thats vasically 1% of the population.

so multiply 6.72941176471 * 100

so now you have

672.941176471 and you can round this to 673 kids.

and you know its right since 85% of 673 is 572.05 and you can sound to 572

Enter the equation of the line meeting the given conditions. Please put the equation instandard form.
just olya [345]

first, the slope is needed, which is 3-2/3--3 which is 1/6 and so this will be y=(1/6)x+b which then we'll input (3,3) which is 3=2+b or b=1 so the equation is y=(1/6)x+1

A store is designing the space for rows of nested shopping carts. Each row has a starting cart that is 4 feet long, followed by
stich3 [128]

Answer:

Each nested carts is of the length of 1.5 feet.

Step-by-step explanation:

Each row has a starting cart that is 4 feet long, and the nested carts are next to it.  

It is measured that a row of 13 nested carts has a length of 23.5 feet.

Therefore, the original length of 13 nested carts is (23.5 - 4) = 19.5 feet.

So, each nested cart add to the length of the row, \frac{19.5}{13} = 1.5 feet.

Again, a row of 18 nested carts to be 31 feet long.

Therefore, the actual added length of 18 nested carts is (31 - 4) = 27 feet.

So, each nested cart add to the length of the row, \frac{27}{18} = 1.5 feet.

So, each nested carts is of the length of 1.5 feet. (Answer)

If _____, use threshold braking any time you need to brake hard.
Inessa [10]

Answer:

The correct option is;

A. You don't have ABS

Step-by-step explanation:

A car braking system works by the friction action the break pad applies on the wheels, when the break is applied with much force, due to hard and sudden breaking of the motion of the vehicle, the break pad stops the rotation of the wheels but the vehicle could however continue skidding due to the high initial momentum

The being skidding vehicle in a situation of kidding increases the likelihood for an accident as the the vehicle can no longer be controlled at the steering either

Threshold braking is the technique of bringing the vehicle to a stop or slowing down in the shortest time possible by applying an optimum breaking force during breaking

Anti-lock Braking System is a safety feature that prevents skidding by keeping the wheels of the vehicle or aircraft from locking when excessive break is applied such that traction maintained between the wheels and the road.
