If the radius of a cricle is increased by 75 percent then its circumference will be increased by?

The cricle's circumference is a linear function of its radius, so they change in direct proportion.If the radius increases by 75%, the circumference also increases by 75%.


What is the radius of a pencil?

You can use the circumference of the pencil and the circumference formula to find the radius. Set the measured circumference equal to 2pi*radius and solve. I measured it to about .75 of an inch, so: .75=2pi*radius r=.75/2pi


What is radius of a circle with circumference of 75 in?

What i the radius when circumference is 75 cm?

To find the radius when the circumference is 75 cm, you can use the formula for circumference: ( C = 2\pi r ). Rearranging the formula to solve for the radius ( r ) gives ( r = \frac{C}{2\pi} ). Substituting the circumference, you get ( r = \frac{75}{2\pi} ), which is approximately 11.94 cm.
