Question

find the circumference and area of the circle whose radius is 17of 1/2mm... ​

Answer 1

Given:

Radius = 17 of 1/2 = 8.5 mm

To Find:

The circumference and the area of the circle.

Formulas Used:

Circumference of a circle = 2πr

Area of a circle = πr squared

Solution:

By using the given value, we get

Circumference of the circle = 2 × 22/7 × 8.5

Circumference of the circle = 53.4 mm (approx.)

Area of the circle = 22/7 × 8.5 × 8.5

Area of the circle = 227.1 mm squared (approx.)
