<u>Equation of a circle</u>
where:
- (a, b) is the center
- r is the radius
From inspection of the graph:
- center of the circle = (-2, 1)
- radius of the circle = 3
Substitute the found values into the formula:

Answer:
- area ≈ 59.441 in²
- lateral area ≈ 352.671 in²
- surface area ≈ 471.553 in²
Step-by-step explanation:
1. The area of the regular polygon base of the prism can be found from the formula ...
A = (nr²/2)sin(360°/n) . . . . where r is the radius and n is the number of sides
Filling in the numbers and doing the arithmetic gives ...
A = (5·5²/2)sin(72°) ≈ 59.441 . . . square inches
__
2. The lateral area is the product of the height and the perimeter. The perimeter of the regular polygon can be found from ...
P = 2nr·sin(180°/n) = 50sin(36°) ≈ 29.389 . . . inches
Then the lateral area is ...
LA = Ph = (29.389 in)(12 in) = 352.671 in²
__
3. The total area is the area of the two bases together with the lateral area:
S = 2·(base area) + (lateral area) = 2(59.441 in²) + 352.671 in²
S = 471.553 in²
Answer:
The expression could be used to verify g(x) is the inverse of f(x) is letter b which is 1/5(5x-25)+5
Step-by-step explanation:
-2x(4x² - 5x + 3) Distribute/multiply -2x into (4x² - 5x + 3)
(4x²)(-2x) - (5x)(-2x) + (3)(-2x)
-8x³ + 10x² - 6x
