Answer:

you need the formula for the cone , Korc

Step-by-step explanation:

formula for cone = $\frac{1}{3}$ *π* $r^{2}$ *h

they tell us that the diameter is 8 so r = 4

and that h = 9

volume of cone = $\frac{1}{3}$ *π* $4^{2}$ *9

VoC = 150.796

VoC = 150.8 ( to the nearest 10th)

The perimeter of the base of a square pyramid is 16 feet and it stands 20 ft tall. Calculate the volume.

Vikentia [17]

Answer: $1706.67 feet$

Step-by-step explanation:

Formula: Volume = $\frac{1}{3} \alpha^{2}h$

a is the length of the base's edge and h is the height. Since 16 is the length we would square it as it is the length, then we would multiply it by the height which is 20 ft.

<u>Steps: Multiply</u>

Volume = $\frac{1}{3} \alpha^{2}h$

= $\frac{1}{3} * 16^{2} * 20$

= $1706.67 feet$
