Question

If radius of circle is 35m then find its area and diameter.​

Answer 1

Answer:

Area = 3850 cm²

Diameter = 70 cm

Step-by-step explanation:

Given -

Radius of a a circle = 35 cm

To find -

Diameter and Area of circle

solution -

Circle's area = πr²

= 22/7 × 35 × 35

= 22×35×35/7

= 22×35×5 cm²

= 3850 cm²

Diameter is twice of radius, so

Diameter = 2×radius

= 2×35 cm

= 70 cm

Hence area of circle = 3850 cm²,

And diameter = 70 cm
