Question

Find the total surface area of the cylinder Leave the answer in terms of π. radius 3.5 height 6

Answer 1

Answer: 133/2π

Step-by-step explanation:

Area of ends:

Area of Circle = πr²

π3.5²=49/4π

There are two ends so you multiply that by 2 to get 49/2π

Area of Rest:

First, you need to find the circumference using the equation: πd

πx7=7π

Then to find the area you just need to multiply 7π by the height

7π x 6 = 42π

Total surface area

You now just need to add them together

49/2π + 42π = 133/2π
