Q no F. Find the perimeter...

Answer»

given diameter of the CIRCLE = 28cm

we know that diameter is double the length of it's radius.

therefore length of it's radius = 28/2 = 14cm

now, PERIMETER of circle is KNOWN as it's circumference.

formula to find circumference of a circle is 2πr.

hence, it's circumference = 2πr

= 2 × 22/7 × 14

= 2 × 22 × 2

= 88CM
