Answer: 3900
ft^3
if you use the formula on how to find the volume of a cone
V=r^2*h/3
you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900 ft^3
3x^2 / 4 = 48
Multiply both sides by 4 to get rid of the four on the left.
3x^2 = 192
Divide both sides by 3
x^2 = 64
The square root 64 to get x
Remember there are two answers
x = 8 and x = -8
Let the radius of the circle be r. Then the line from the external point through the center of the circle which extends to the far point on the circle has length 3r .By the tangent - secant theorem
t^2 = 3r * r = 3r^2 ( where t is the length of the tangent).
So t = √(3r^2) = √3r answer.
