Question

The radius of a circle is given 14cm Find
a. The diameter of the circle.
b. The circumference of the circle.

Answer 1

Step-by-step explanation:

Diameter = 14cm.

138

4.0

So radius = 14/2 cm = 7cm.

Circumference = 2 pi r.

So, circumference = 2 × 7 × 22/7 = 44cm.

Hope this helps you

Answer 2

Step-by-step explanation:

radius, r = 14cm

a) diameter, d = 2r = 2×14 = 28cm

b) circumference/ perimeter = 2πr = 2 × 3.14 × 7 = 28 × 3.14 = 44cm
