How to find radius and circumference diameter equal to 24 metre

Answer 1

Solution:

Diameter = 24 meter

We have to find:-

• Radius

• Circumference

Formulas we will use :-

• Radius = Diameter / 2

• Circumference = 2πr

Now,

Radius = 24 / 2 = 12 meter

Circumference = 2πr = 2 × 22 / 7 × 12 = 528 / 7 = 75.42 meter ( Taken till two Decimal places. )
