Answer:
314.16 in²
Step-by-step explanation:
If the diameter is 20", then the radius is 10" (1/2 the diameter).
Area of a circle is ²
So, π 10² = 100π = 314.16 in²
Answer:
Step-by-step explanation:
<u>Given</u>
- The dimensions of the lot are (6+x) feet and (6−x) feet
- The dimensions of the house to be (2+x) feet and (2−x) feet
Area of the yard = Area of the lot - Area of the house
<u>Area of the yard:</u>
- (6 + x)(6 - x) - (2 + x)(2 - x) =
- 36 - x² - 4 + x² =
- 32 square feet
<u>If the house is extended, then the area of the yard will change as:</u>
- (6 + x)(6 - x) - (4 + x)(4 - x) =
- 36 - x² - 16 + x² =
- 20 square feet
Answer:
6
Step-by-step explanation:
Put the given point into the equation and solve for a.
f(-2) = a(-2 +3)² -4 = a -4 = 2
a = 6 . . . . . add 4
The a-value in the equation is 6.
