Question

HELP ASAP!!!!The Singh family ordered a large pizza with a diameter of 20 inches for dinner. If one of the members of the family ate one eighth of the pizza, how many square inches of pizza are remaining? Use 3.14 for π.

274.75 square inches
39.25 square inches
314 square inches
157 square inches

Answer 1

Answer: 274.75

Explanation:

Diameter=20

r= 20/2=10

A= π
`r^(2)`

= 3.14*10*10

= 314 square inches

1/8 of 314 = 39.25

So, are of remaining pizza = 314-39.25

= 274.75 square inches

Answer 2

274.75 in²

Explanation:

Area of a circle = πr² = (3.14)(20/2)² = 314 in²

(314 in²)(1/8) = 39.25 in²

Pizza remaining = 314 - 39.25 = 274.75 in²
