Question

Is the radius of a cylinder is 10 cm. Find its total surface area and diameter

Answer 1

Radius of the circle = 10cm

So, Diameter = 10 × 2 = 20cm

Area of the circe = πr²

= 22 × 10cm × 10cm / 7

= 2200 / 7 cm²

∴ The Area and Diameter of the circle whose Radius is 10cm is 2200 / 7 cm² and 20cm respectively.

Hope this helps
