IF ANYBODY IS GOOD WITH CIRCLES HELP! HELP I NEED HELP WITH CIRCUMFERENCE!! What is the radius of a circle with circumference of 50 cm? Round your answer to the nearest whole number. Use π = 3.14. A. 4 cm
B. 3 cm
C. 8 cm
D. 7 cm

7.96 cm or rounded, it is C. 8

Step-by-step explanation:

The accurate number is 7.961 but round that up to 8

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
