Question

the difference between the circumference and diameter of a circle is 150m.what is the radius of that circle​

Answer 1

Answer:

• diameter is 150m.diameter mean 2 halfs of radius .150/2.
• 150/2=75.
• 75 is the radius.

Answer 2

Circumference=2πr

Diameter=2r

difference between circumference and diameter=150m

2πr-2r=150

2r(π-1)=150

r(π-1)=75

r=75/(π-1)

r= 75/{(22/7)-1}

r=75/(15/7)

r=7×75/15=7×5

r= 35m
