Remember for circle equations.
C = 2 pi r
Algebraically rearrange
r = C / ( 2 pi)
Substitute
r = 52 / ( 3.1416 x 2)
Cancel down by '2'
r = 26/ 3.1416
r = 8.27605...
r = 8.28 ( To nearest hundredth).

What is circumference of circle with a radius of 1.75 inches?
C= pi x 2 x radius or C= pi x diameter. Remember, diameter is 2 x the radius, so: C= 3.14 x 2 x 1.75 or C= 3.14 x 3.5 C= 10.99(or 11 rounded to the nearest whole #)
If radius is 13 inches what is circumference to the nearest 10th of an inch?
If r = 13 inches then C = 81.7 inches
S equals C plus M C equals 14 M equals - 2.50 find the value of the variable that is not given Round to the nearest hundredth if applicable?

52 pt equals how many c?
52 pt * (2 c / 1 pt) = 104 c
What is the radius of a circle with circumference of 42.1 round to the nearest tenth?
The formula for circumference is C = Pi x D where Pi = 3.1416 and D is the diamter. The radius is one-half of the diameter. You can find the radius by applying the formula for circumference and solving for D, then dividing by 2: 42.1 = 3.1416 x D 42.1 ÷ 3.1416 = D 13.4008 = D D ÷ 2 = R 13.4008 ÷ 2 = R 6.7 = R
