a toy rocket is fired into the air from the top of a barn. it's height h above the ground in yards after t seconds is given by the function h(t)= -5t^2 + 10t+ 20. the initial height of the rocket is ? feet about the ground

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
