Area = pi * r * r = 254.34 pi = 3.14 so r * r = 254.34 / 3.14 = 81 so r = 9 cm The circumference = 2* pi * r = 2 * 3.14 * 9 = 56.52 cm
A square has four equal sides. So the side length is 13 cm. The area, 13 cm x 13 cm, is 169 square centimetres.
C = 2 pi r (divide by 2pi to both sides) C/2pi = r (substitute 13 pi cm for C) r = (13 pi cm)/(2 pi) = (13/2)(pi/pi) cm = 6.5 cm
r = 2.07 cm

The circumference of a circle of radius r cm is 2*pi*r cm so the length of the semi-circular arc is pi*r cm. The length of the diameter is 2*r cm so the total length is (pi + 2)*r cm
33.02 cm Algebraic Steps / Dimensional Analysis Formula 13 in* 2.54 cm 1 in = 33.02 cm
13 inches is 33.02 cm
13 cm = 5.12 inches.
13 ft = 396.24 cm
If the radius is r cm and the height is h cm, then Volume = pi*r^2*h cm^3 and Surface area = 2*pi*r(r+h) cm^2
The area of a circle with radius r is pi*r*r where pi = 3.1416 approx. When r = 6 cm, the area is 113.1 sq cm.
It is: 2*pi*13 cm
