$23.10

$18.66

Answers

$17.49 because you multiply 22 by .25 getting 5.5. You subtract that from the original 22 getting 16.5 which you then multiply by the sales tax .06. Add the tax amount to the 16.5 to get 17.49.

PLEASE HELP WITH MATH. BEST GETS BRAINLIEST.Celina is buying fabric scraps to make koozies for her glasses. Each glass is cylindrical with a diameter of 3 inches and a height of 4 inches. The koozies will cover only the sides of the glasses. What is the amount of fabric she will use? What does this amount represent? Use 3.14 for pi. Show your work.

Answers

What you're looking for here is the surface area of the sides of the glasses (what the koozies will cover). This is also what the amount represents.

The surface area of the sides is equal to the perimeter of the base times the height of the cylinder. It makes sense logically because the sides are basically the perimeter of the base, raised all the way up along the cylinder.

SA = perimeter x height
SA = pi x diameter x height
SA = 3.14 x 3in x 4in
SA = 37.68 in^2

She will use 37.68 square inches of fabric.

A cone has a base radius of 7 centimeters and a height of 21 centimeters.What is the volume of the cone?

A.
28π cm3

B.
49π cm3

C.
147π cm3

D.
343π cm3

Answers

Substitute the values of the radius (r=7), the height (h=21), and an approximation of Pi (3.14) into the formula to find the volume of the cone.
V≈+1/3⋅3.14⋅7^2⋅21

Simplify.
Write 3.14 as a fraction with denominator 1.
V≈+1/3⋅3.14/1

Combine 1/3 and 3.14/1 to get 3.14/3.
V≈+3.14/3

Replace back in to larger expression.
V≈+3.14/3⋅7^2⋅21

Divide 3.14 by 3 to get 1.04666667.
V≈+1.04666667⋅7^2⋅21

Raise 7 to the power of 2 to get 49.
V≈+1.04666667⋅49⋅21

Multiply 1.04666667 by 49 to get 51.28666667.
V≈+51.28666667⋅21

Multiply 51.28666667 by 21 to get 1077.02.
V≈+1077.02

V≈+1077.02cm^3
