(2) height 25cm diameter 1.2cm

Question (2) The curved surface area of a cylinder is 251.36cm and the height is 8cm. Calculate it's base radius

Answer 1

Step-by-step explanation:

Questions (1)

Answer:-(a)Height=10cm

Radius=6cm

curved surface area of a cyclinder=2πrh(formula)

2×22/7×6×10

18480/7cm2

2640cm2

(b) Height=10cm
