Download Solution PDFGiven:
Initial radius of the circle = r
New radius of the circle = 8r
Formula Used:
Circumference of a circle = 2πr
Calculation:
Initial circumference = 2πr
New circumference = 2π(8r)
New circumference = 16πr
Increase in circumference = New circumference / Initial circumference
⇒ Increase in circumference = 16πr / 2πr
⇒ Increase in circumference = 8
The circumference increases 8 times from the previous circumference of the circle.
