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
