Question

circumference is 48.4 cm find the radius and diameter
​

Answer 1

Given:

Circumference of the circle is 48.4 cm

To Find:

The radius and the diameter of the circle.

Formula Used:

Circumference of a circle = 2πr

where r is radius.

Solution:

According to the question,

2πr = 48.4 cm

πr = 48.4/2 cm = 24.2 cm

r = 24.2 × 7/22 = 7.7 cm

We know that Diameter = Radius × 2

So, Diameter = 7.7 × 2 = 15.4 cm

Answer:

The radius of the circle is 7.7 cm.

The diameter of the circle is 15.4 cm.
