Question

if the circumference of a circle exceeds its diameter by 15 cm then the diameter of the circle is

Answer 1

Answer:

32.1

Step-by-step explanation:

Let, diameter = X

circumference = 2πr

Therefore ,radius equal to X / 2

X + 15 = 2 π r

X + 15 = 2 π X/2

X + 15 = 3.14 X

2.14 X = 15

X = 32.1
