Question

if the diameter of a circle is 5.4m, what will be it's radius and circumference​

Answer 1

Circle

Solve for radius

r=2.7m

d Diameter

5.4

Answer 2

Given :

Diameter of circle = d = 5.4 m

Solution:

Radius(r) = d/2 = 5.4/2 = 2.7 m

Circumference of circle = 2πr

                                       = 2 * 3.14 * 2.7

                                       = 16.956 m
