Answer:
<u>The area of a pizza made in that circular pan is 452.39 inches²</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Diameter of the circular pan = 24 inches
Radius of the circular pan = 24/2 = 12 inches
2. What is the area of the pizza?
Let's use the formula of the area of a circle, this way:
Area = π * r²
Substituting with the real values, we have:
Area = 3.1416 * 12²
Area = 452.39 inches²
<u>The area of a pizza made in that circular pan is 452.39 inches²</u>
The area of the house is the amount of space on the house.
- The length of the addition is x + 20
- The area of the original house is
<h3>The length of the addition</h3>
The area of the addition is given as:
Expand
Factorize
Factor out x + 20
The width of the addition is x - 10.
Hence, the length of the addition is x + 20
<h3>The area of the original house</h3>
The dimension of the original house is
x + 20 by x + 10
So, the area is:
Expand
This gives
Hence, the area of the original house is
