Oil is leaking from an oil tanker, and an expanding circle of oil is spreading on the ocean. The radius, r, of the circle measured in inches is modeled by the function r(s)=3 sqrt s, where s is time in seconds. The area of the spill when s=5 seconds is ___ pi square inches.

Step-by-step explanation:

The radius, r of the expanding circle of oil is modeled by the function:

, where s is time in seconds.

When s=5

Area of a circle

Therefore, area of the oil spill when s=5 seconds is:

The area of the spill when s=5 seconds is 45pi square inches.

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree

the solution is h=10 because you add 9 to each side of the equation.
