Question

Please solve this ques with full explanation​

Answer 1

Step-by-step explanation:

The Circle Formulas are expressed as,

Diameter of a CircleD = 2 × rCircumference of a CircleC = 2 × π × rArea of a CircleA = π × r2

Example :-

A circle has a radius 8 cm. Calculate its diameter, area and circumference.

Solution

Given parameters are,

Radius, r = 8cm

Diameter of a circle is given by

2r

= 2 × 8 cm

= 16 cm

Area of a circle is given by

π r2

= π × 64

= 201.088 cm2

Circumference of a circle is given by

2 π r

= 2 × π × 8

= 50.272 cm
