How would you measure the volume of a metal sphere?

Answer 1

1. Measure the radius of the sphere.

2. Cube the radius.

This is basically multiplying the radius by itself three times, (RxRxR).

3. Multiply the answer by pi. (If this is a school homework assignment, and the instructions say "exact value", just write the greek letter pi. Otherwise, use the decimal equivalent, 3.14159.)

4. Multiply the previous answer by four thirds.

There are several ways to do this: * Option 1: on your calculator, enter in the improper fraction, four thirds, then multiply it with the answer from the previous step. * Option 2: If your calculator does not allow you to input fractions, multiply the answer to the previous step by four, then divide it by three. * If you have simply written the greek letter pi, instead of multiplying by 3.14 or something similar, then multiply only the coefficient of pi by 4. Then put the whole thing in the numerator of a fraction, with 3 as the denominator. Take to lowest terms.
