Answer:

Step-by-step explanation:

Hi, what you do first is:

P (which stands for perimeter)= L + W + L + W (L stands for length and W stands for width)

P= 16in + 12in + 12in + 25in

P= 28in + 37in (I added 16 to 12 and 12 to 25)

P= 65in.

If a cone has a volume of 338 cm^3 and a radius of 6 cm, how tall is it?

Anna35 [415]

The formula for the volume of a cone is V = πr²h ÷3

You are solving for the height, h.

V = 338 cm³ and r = 6 cm

338 = π(6)²h÷3

338 = π36h÷3

338 = π12h

28.16 = πh

8.965 = h

The height of the cone is around 9 cm.
