JordanOh, dude, no way! 2πr is not linear; it's actually the formula for calculating the circumference of a circle. Linear functions are like those boring straight lines that have a constant slope, not the cool, curvy stuff you find in circles. So, yeah, 2πr is definitely not linear, but it's got its own circular charm.

What is the radius if area equals 289 pi?
Recall the equation A = pi * r^2. You've given the information that A = 289 pi. Now, simply solve the equation for r: A = pi * r^2 289 pi = pi * r^2 289 = r^2 sqrt(289) = r 17 = r
Can the circumference and the area of a circle both have the same answer?
C=2(pi)r A=(pi)r2 If C=A, then 2(pi)r=(pi)r2. Divide both sides by r: 2(pi)=(pi)r. Divide both sides by (pi): 2=r. Therefore, if the radius of a circle is 2 ft., the circumference is 2 sq. ft.
What is the radius of a circle with circumference of 8 inches?
C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi
What is the formula for the lateral surface area of a cylinder?
2(pi r 2) + (2 pi r)* h
The circumference of a circle is 60 pi cm what is the radius of the circle?
let c bet the circumference and r be the radius. c = 2 pi r since c is 60 pi 60pi = 2 pi r divide both sides by 2 pi 30 = r
