31.4. circumference formula is pi x diameter, and the formula for diameter is radius x 2. so, 5x2= 10 and 10 x 3.14= 31.4
Answer is x= 3 or x= -2
x(x+2) -3 (x+2) = 0
(x+2) (x-3) =0
x+2=0
x-3=0
so..
x=-2
x=3
hope this helped a bit good luck :)
Answer: it think the answer is 8
Sorry if I’m wrong
Answer:
radius=2, height=3
Step-by-step explanation:
diameter= 2x the radius therefore 4/2=2=radius
cylinder volume formula=πr^2h
volume=12π
height= v/πr^2=12π/π*2^2=12π/π*2^2=12π/4π=3
hope this helped!
The answer is -10x^3+23x^2-24x+18
