1(4r-5.7) = 45

First multiply 1 to 4r and -5.7

4r - 5.7 = 45
4r - 5.7(-5.7) = 45 (-5.7)
4r = 39.3
4r/4 = 39.3/4

r = 9.825

9.825 should be your answer

Hope this helps

Answer:

$20\:\mathrm{in}$

Step-by-step explanation:

The lateral surface area of a cone is given by $A=\pi r\ell$ , where $r$ is the radius of the base of the cone and $\ell$ is the cone's slant height.

Solving for $\ell$ :

$200\pi=10\pi\ell,\\\ell=\frac{200\pi}{100\pi}=\boxed{20\:\mathrm{in}}$

*Note: It is implied that the surface area of 200 pi square inches is lateral surface area and not total surface area, because it is impossible to obtain a total surface area of 200 pi with a radius of 10 inches.
