253 in²
Step-by-step explanation:
Surface area of a cylinder= 2πr (r+h)
The radius is not shown.
Radius= diameter/2
= 7/2
= 3.5 in
Surface area= 2xπx3.5 (3.5+8)
= 253 in²
*r=radius
h=height
I used the π value from my calculator.
P.S. You can substitute π for 3.14. If you round it to the nearest whole number, you will still get the same answer. Hope this helped!
The picture shows the diameter and the height. First, find the radius from the diameter by dividing by 2.
