Answer:

Circumference: 50.27 cm

Area: 201.06 cm²

Step-by-step explanation:

Hi there!

<u>1) Determine the circumference</u>

C=\pi d where d is the diameter of the circle

Plug in the diameter (16 cm)

C=16\pi\\C=50.27

Therefore, the circumference is 50.27 cm when rounded to the nearest hundredth.

<u>2) Determine the area</u>

A=\pi r^2 where r is the radius

Plug in the radius (16/2=8)

A=\pi (8)^2\\A=64\pi\\A=201.06

Therefore, the area of the circle is 201.06 cm² when rounded to the nearest hundredth.

I hope this helps!

A caution flag on the side of a road is shape like a trapezoid. One base of the trapezoid is 1 ft shorter than the other base.Fi
EleoNora [17]

Answer:

The lengths of the base are 2 ft and 3 ft

Step-by-step explanation:

Let one base of the trapezoid be x ft

Then the other parallel side is equal to x+1 ft

Given height of the trapezoid = 4 ft

Area of the trapezoid = 10 ft^{2}

We know that the area of trapezoid=\frac{1}{2}* (height)(sum of the parallel sides)

10=\frac{1}{2}*(4)*(x+x+1)

2x+1=5

x=2

The lengths of the base are 2 ft and 3 ft

A number cube is labeled 1 through 6. What is the probability of NOT<br> rolling a 2?
Andre45 [30]

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

 1       2       3      4      5       6

1/6     1/6    1/6    1/6    1/6    1/6

Every time the cube is rolled  there is a 6/6 chance of any number comes up

1/6  +   1/6  +  1/6 +   1/6 +   1/6  +  1/6   = 6/6     or  1  

What is the probability of NOT rolling a 2? Any other number

 1        2       3        4        5         6

1/6  +   0  +  1/6 +   1/6  +  1/6 +   1/6   =   5/6    or    0.8333

Item 8 Question 1 A roller coaster ride holds a total of 48 passengers. The ratio of males to females on the ride is 5 : 7. Let
anastassius [24]
Here are the equations
x+y=48
x/y=5/8


but here's how I would solve it

5+7=12
48=12units
divide by 12 both sides
4=1unit

males=5 unit
4=1unit
times 5
20=5unit=males

females=7unit
4=1unit
times 7
28=7unit=females

What adds to 1 and multiples to -90
wariber [46]

Answer:

+10 and - 9

Step-by-step explanation:

If we consider the multiples of - 90

± 1, ± 2, ± 3, ± 5, ± 6, ± 9, ± 10, ± 15, ± 30, ± 90

The combination of multiples which multiply to - 90 and add to + 1 are

+ 10 and - 9

since 10 × - 9 = - 90 and 10 - 9 = 1
