Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = \frac{1}{3}\pir²h

V = \frac{1}{3}(3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = \frac{4}{3}\pir³

113.04 = \frac{4}{3}(3.14)r³

113.04 = 4.19r³

26.98 = r³

3 ≈ r

To find the area of a trapezoid, it’s 1/2(base 1 + base 2) x height.
so in this case, base 1 is 16 (add 12+2+2) (the top one) and base 2 is 12 (the bottom one) and the height is 9.
you input all the values in the formula and you get 126in.
hope this helped:)
