Question

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

Answer 1

Answer is 35m

Step-by-step explanation let radius be r

:diamete=2r

And circumference = 2 pie r

Now accorfing to question

2pie r - 2r = 150

Taking 2r common

We have

2r (pie -1) =150

Now pie = 22 /7

Then

2r (22/7 -1) = 150

2r (22 -7 /7 ) = 150

2r = 150 × 7 /15

r = 150 ×7 /15 ×2

r = 35 m
