first let's find the are of the whole pizza

The pizza is circular in shape

So we can find its area using the formula of area of a circle


A=\pi r^2

where r is the radius

From the question, diameter = 10

Radius is half of diameter, hence r = 5 cm

Substitute the value of r = 5 and pie =22/7 in the formula and evaluate


A=(22)/(7)*5^2
=78.571

Since Angie ate 1/4 of the pizza, we will find 1/4 of 78.571

= 19.64 square inches
