Find the volume of a right circular cone that has a height of 15 ft and a base with a radius of 7. 9 ft

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

The answer will be y=-5+0 because the slope is -5 and the it has to go through y-axis 0
