Answer -15 because it would be 15 but the negative would be turned into a negative again
Answer:
π = V/(2r²+2rh)
Step-by-step explanation:
"Solving" for something means to isolate it on one side of an equation. Because both terms on the right side of the equation have π in common, we can factor it out. Then from there, you just divide the rest of it on both sides to isolate π. It should look like this:
V=2πr^2 + 2πrh
V=π(2r² + 2rh)
V/(2r² + 2rh)=π

Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.
