Answer:
60
Step-by-step explanation:
Simplify the following:
4×9^2/27×5
9^2/27×5 = (9^2×5)/27:
4×(9^2×5)/27
4×(9^2×5)/27 = (9^2×5×4)/27:
(9^2×5×4)/27
9^2 = 81:
(81×5×4)/27
81/27 = (27×3)/27 = 3:
3×5×4
3×5 = 15:
15×4
15×4 = 60:

<u>Area of the triangle formula:</u>
b is given: AB = 9 in
<u>Line CD is added for h, finding its value:</u>
- CD/BC = sin 75°
- h/7 = 0.9659
- h = 7*0.966
- h = 6.76 in
<u>Then finding the area:</u>
- A = 1/2*6.76*9 = 30.42 in²

Answer:
A = (1/2)Cr . . . or . . . A = C^2/(4π)
Step-by-step explanation:
The diagram shows the area of the circle being redrawn as a parallelogram with the length of it being half the circumference and the height of it being the radius of the circle.
The area of the parallelogram is the product of its length (C/2) and its height (r), so you can compute ...
A = (1/2)Cr
___
Given only the circumference, C = 2πr, you can find the value of r by dividing by its coefficient:
C/(2π) = r
Using this in the above formula, the area can be found from the circumference only as ...
A = (1/2)C·(C/(2π))
A = C^2/(4π)
