Answer:
r = √(V/πh)
Step-by-step explanation:
V=π*r^2*h solve for r
divide both sides by πh
V/πh = π*r^2*h/πh
Simplify
V/πh = r^2
so r = √(V/πh)

Answer:
1725 ft²
Step-by-step explanation:
The formula for the area of a trapezoid is ...
A = 1/2(b1 +b2)h
Here, the bases are given as 65 ft and 50 ft, and the height is 30 ft. Then the area is ...
A = 1/2(65 ft +50 ft)(30 ft) = (1/2)(115 ft)(30 ft) = 1725 ft²
You tell the salesman your lawn area is 1725 square feet.
Answer:
d<3
Step-by-step explanation:
-7d+8>29

-7d>21
since you divide by negative you switch
d<3
that is your answer
If ir means not, then irrational means not rational. Pi is and irrational number.
