Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2

I think the answer is C sorry if I'm wrong but hope I helped
The answer to ur problem is 8.125 or 65/8
Answer: 455 possible outcomes
Step-by-step explanation:
If there are 3 positions and 15 candidates, you multiply 15 by 14, then by 13 to get the number of possible outcomes times 6.
This is because once a candidate gets a position, there will be 1 less candidate without a position each time.
15 * 14 * 13 = 2,730
Now, since there are only 3 positions, the first position has 3 possible ways, the second position has 2 possible ways, and the third position has 1 possible way.
3 * 2 * 1 = 6
2,730 / 6 = 455
