Answer:

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 7 m radius

h = 2 m

<u>plugin values into the formula</u>

surface area = 2πrh + 2πr²

= 2π (7) 2 + 2π (7)²

= 87.965 + 307.867

= 395.841 m²

h = 2 m

Plugin

2π (7) 2 + 2π (7)²

multiply into itself than add

Answer:

$10,922\frac{2}{3}\ mm^{3}$

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

where

b is the length side of the base

h is the height of the pyramid

In this problem we have

$b=32\ mm$

$h=32\ mm$

substitute

$V=\frac{1}{3}(32^{2})(32)=(32,768/3)\ mm^{3}$

Convert to mixed number

$\frac{32,768}{3}=\frac{32,766}{3} +\frac{2}{3} =10,922\frac{2}{3}\ mm^{3}$
