Answer: Let x be the
Step-by-step explanation:
Area of a circle=pi x r^2= 3.14 x 8^2(half of the radius)=3.14 x 64=200.96
area of triangle= 1/2 bh=1/2(16)(8)=1/2(128)=64
200.96-64=136.96 sq.ft
Answer:
The least common multiple (LCM) for nine and six is 18.
I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.



Answer: n² - 3n - 20 = 0
That doesn't factor so there is no integer n solution.
That means there are no polygons with 10 diagonals.

Answer:
Number of cube fit in prism = 24 cubes
Step-by-step explanation:
Given:
Side of cuboid = 1cm , 2cm , 2 1/2
Find:
Number of cube fit in prism
Computation:
Number of cube fit in prism = Volume of prism / Volume of cube
Number of cube fit in prism = (1)(2)(3/2) / (1/2)³
Number of cube fit in prism = 24 cubes
