Answer:

Lateral area =

pi * (radius) * √ [ height ^2 + radius^2 ] =

pi * ( 4 ) * √ [ 4^2 + 3^2 ] =

pi * ( 4 ) * √25 =

pi * ( 4 ) * (5 ) =

20 pi units^2 ≈ 62.8 units^2

Hello!

I will make approximations below to the nearest whole number

A. 2√32≈11

B. 5+√18≈9

C. √24≈5

D. √52-3≈4

E. 3√14≈11

F. √20+√26≈10

Based off of what we see here our even numbers are $\boxed {D}$ and $\boxed {F}$ .

I hope this helps!

Answer:

Step-by-step explanation:

Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: • 60° and 120° are supplementary angles.
