Leslie buys a large circular pizza that is divided into eight equal slices. she measures along the outer edge of the crust from one piece and finds it to be 5.5 inches. what is the diameter of the pizza to the nearest inch? a. 7 inches b. 8 inches c. 14 inches d. 12 inches what is the total surface area of a rectangular prism that is 4 inches deep, 5 inches high, and 15 inches across? a. 300 in² b.310 in² c.270 in² d.155 in²

Question 1:

A large circular pizza that is divided into eight equal slices.

Circumference of a whole pizza (circle) =

Since a pizza is divided into 8 equal parts.

So, circumference of 1 part = = inches

The measure of outer edge of the crust of one piece = 5.5 inches.

r = 7 inches

Therefore, diameter = 2r = 2 7 = 14 inches.

Question 2:

Given length = 15 in

Breadth= 4 in

height = 5 in

We have to determine the surface area of rectangular prism.

Surface area of rectangular prism =

=

=

= 2 155

= 310

So, the surface area of rectangular prism is 310.
