The earth's circumference, measured through the poles, is exactly 40, 000, 000 m (according to an early standard of the meter). What is the radius of the earth, R? R = m. b. The surface area of the earth is given by A = 4x x R'. What is the area A? A = m. c. Using the unit's conversion 1 inch = 2.54 cm, convert the volume V = 302 in' into a volume in cubic cm (em') and in liters. (1 L = 1000 cm'). Show your steps in below! V = cm = 5.
