Answer:
Step-by-step explanation:
Patrick pizza parlor is famous for its giant circular pizza, which has an area of 1519.76 square inches. The pizza is circular in shape. The formula for determining the area of a circle is expressed as
Area = πr^2
π is given as 3.14
Therefore,
1519.76 = 3.14 × r^2
r^2 = 1519.76/3.14 = 484
Taking square root of both sides of the equation, it becomes
r = √484 = 22 inches
Diameter = 2 × radius.
Therefore, the diameter of the giant pizza is 2 × 22 = 44 inches
Well, one thing they ahve in common is that they are both adding or subtracting the same numbers and of course, they are both expressions.
They are different because one expression is subtract both numbers while one expression is adding both numbers.
8 - 15 = -7
8 + 15 = 23
Best of Luck!
