10.) Find the radius of a cylinder that has a height of 5 inches and a volume of 251 2 cubic inches.

Radius is 4.297

Step-by-step explanation:

Hieght=5

Surface Area=251

Its r = 3.99898596 in

Step-by-step explanation:

It should be the answer if the volume is 251.2. But it confuses people like is it 251 2 or 251.2. Hope that helps

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
