Question

The diameter of a circular park is 30m. Find its surface area.

Answer 1

Answer:

707.14 m²  

Explanation:

given ,

diameter, d = 30 m

radius , r = ( 30/2 ) m

               = 15 m

∴ area of a circle = πr²

                            = 22/7 × (15)²

                            = 22/7 × 225

                            = 707.14 m²
