Question

find the curved surface area of a cylinder whose height 5 cm and the radius of the base is 7 cm?​

Answer 1

Answer:  Formula for curved surface area= 2πrh

Now,given   r=7cm

                  h=5cm          substitue in the formula

∴ Curved surface area= 2×$\frac{22}{7}$ ×5×7

                      =2×22×5

                  = 220 cm²

Answer 2

Answer:

height=5cm

radius=7cm

curved surface area of cylinder=2πrh

=2×22÷7×7×5

=220cm
