Answer:
You may not recognize this...but the base forms a "Pythagorean" right triangle with legs of 6 and 8 cm
The area of a right triangle is (1/2) ( product of leg lengths)
So...the area of the base = (1/2) (6 * 8 ) = (1/2) 48 = 24 cm^2
And the volume of the prism is just the base area x height = 24 x 7 = 192 cm^2
Step-by-step explanation:
1800
LCM of 10 and 15 = 30
LCM of 6 and 20 = 60
30(60) = 1800
I drew these, as I just did these in math not too long ago. When I shaded it, it was in all four quadrants.
The formula of an area of a circle:

r - a radius
We have r = 14m. Substitute:

If you want an approximate area, you can accept 
Then:
