Question

Help please as soon as possible please and thank you :)

Answer 1

A=
`\pi`r²

A=
`\pi`100

A=314.159

2 slices = 1/4

1/4x314.159=78.5399 centimters squared.

Paragraph:

Firstly, the question has an error. It says that the personal pan pizza is 80 cm³. It should be cm², since it’s area and not volume. You have to figure out the area of the 20 inch pizza using A=
`\pi`r². Since the diameter is 20, the radius is 10, and the area ends up being 314.159. Two slices is 1/4 of the diameter, or 0.25. Multiply 314.159x0.25, and. You get 78.5399 square centimeters. This is just under the 80 that he is allowing himself, so he has made the correct choice.
