Question

The total surface area of a solid right circular cylinder is 660 CM square if the diameter of its base is 14 cm find the height

Answer 1

Answer:

Step-by-step explanation:

TSA = 660 cm

D=14

R=7

H=?

TSA =2πr(r+h)

=2πr(r+h) =660

2×22\7(7+h)=660

2×22×7(7+h)=660

44×7+h=660

7+h=660\44

7+h=15

h=15-7

height = 8 cm

Hope my answer is correct
