Question

The volume of a cylinder 448pie and height 7.find it's curved surface area and total surface area

Answer 1

Answer:

208π

Step-by-step explanation:

22/7 x r x r x h = 448 x 22/7

r x r x h = 448

r² = 448/7

r = √64

r = 8units

TSA = 2πr(r+h)

= 2 x 22/7 x 8 (8 + 7)

=  2 x 22/7 x 104

= 208π
