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
.
