What is the radius of a circle with an area of 50.24 cubic inches? Use 3.14 for pi. Enter your answer in the box.

miss Akunina [59]

Answer:

r=4

Step-by-step explanation:

Area of a circle is

A = pi* r^2

We know the area and 3.14 = pi

50.24 = 3.14 * r^2

Divide each side by 3.14

50.24/3.14 =3.14 /3.14 *r^2

16 = r^2

Take the square root of each side

sqrt(16) = sqrt(r^2)

4 =r

= 360 - 240

= 120 degrees.

I need help with this please

Ierofanga [76]

C is the correct answer

we should find the area of the square and then divide it by 24.
(360/15=24)

$6 \times 6 \times \pi \times \frac{1}{24} = 36 \times \pi \times \frac{1}{24} \\ = 113.04 \times \frac{1}{24} = 4.71$

good luck
