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

Mathematics

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.

A coordinate plane with a line passing through (negative 4, 3), (0, 1), and (4, negative 1). Which linear function is represente
9966 [12]

Answer:

Step-by-step explanation:

If these 3 points are collinear, then we can find the slope of the linear function using any 2 of those points.  Suppose we use (-4, 3) and (0, 1):  

As we move from (-4, 3) to (0, 1), x increases by 4 and y decreases by 2.  Hence, the slope of this lilne is m  = rise/run = -2/4, or m = -1/2.

Using the slope-intercept formula y = mx + b and replacing y with 1, x with 0 and m with -1/2, we get:

1 = (-1/2)(0) + b, or b = 1.  Then the desired equation is y = f(x) = (-1/2)x + 1
