Question

2. A cone has a volume 7,065 in.3 and aheight of 30 inches. What is the radius of thecone?​

Answer 1

Answer:

The radius of cone is 14.996 inches.

Explanation:

The formula of volume of cone is V = 1/3×π×r²×h where r is the radius. In order to find the value of r, you have to substitue the following values into the equation :

V = 7065 in³

h = 30 in

1/3 × π × r² × 30 = 7065

π × r² × 10 = 7065

π × r² = 706.5

r² = 706.5/π

r = √(706.5/π)

= 14.996 inches(3d.p)

Answer 2

39.25

you would divide by 3 then by 30 then divide by 2
