Find two numbers that add up to -15 and multiply to 54 (hint hint, two negatives makes a positive hint hint):
Rewrite the expression:
<em>Finito.</em>
You’re solving for the volume of the cylinder. so the way you would do this is the area of the base of the cylinder (pi times radius squared) which in this case would be 3.14 x 10^2 which is 314. you would then multiply by h, the height, which here is 10. 314 x 10 is 3140.
Well, the formula for a triangle is base times height times 1/2. In this case it would be 21x30. That equals 630. Then, you divide 630 by 2 which is 315. Your answer would be 315 squared.
