Answer:
we have
radius[r]=9ft
height [h]=8ft
now
Volume of cone =1/3×πr²h=1/3×π×9²×8=678.584ft³
Answer:

Answer:
Step-by-step explanation:
The equation of a circle is: 
, where x_1 is the x coordinate of the center, y_1 is the y coordinate of the center, and r is the radius.
In this case, x_1 = -8, y_1 = 14, and r = 4.3589. Plugging these into the equation, we get:
If you want, you can round 4.3589^2 to 19.
Then, the answer would be: .
Hope this helps!
So since this is half a circle, we have to divide the area of a circle by 2. So that would give us 1/2 pi* r^2. We find the radius by dividing 10 by 2. So the radius is 5. Plugging that in for r in 1/2(pi)(r^2) we get 1/2(pi)(5^2) which is 25pi/2. Turning pi into 3.14 we have (25(3.14))/2 which is 78.5/2 which is approximately 39.25 units^2
