It would be d. 215,483 cm³

Step-by-step explanation:

Using the formula for volume of a cylinder which is πr²h and using 3.14 instead of π, we can put the numbers in.

3.14 (15²) (305) = 215,483

r = 15 because to get the radius you have to divide the diameter by 2.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
