Question

if radius of base of a cylinder is 7cm and it's height is 10cm. Find the total surface area.​

Answer 1

given :-

radius of the base of the cylinder = 7cm

height of the cylinder = 10cm

the formula to find the total surface area of a cylinder is = 2πr(h + r)

hence, it's surface area = 2 × 22/7 × 7 (10 + 7)

= 44 × 17

= 748cm²

Answer 2

radius=7cm

height=10cm

TSA of cylinder= 2πr(r+h)

=2×22/7×7×(7+10)

=44×17=748cm
