Find the volume (in cubic yards) of a cylinder with radius 1.2 yards and height 2.6 yards. (Round your answer to one decimal place.)

11.76

Step-by-step explanation:

The formula for cylinder is pi*r^2*h

so substitute and you will get pi*1.44*2.6

Simplify it and you will get 11.75616 or 11.76.

11.8 yards

Step-by-step explanation:

22 dimes and 9 nickels

step-by-step explanation:

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.
