Formula for the area of a quarter circle: A = (pi x r^2) / 4
A = (pi x 2^2) / 4
A = (pi x 4) / 4
A = 4pi / 4
A = 1pi = 3.14 square miles
Hope this helps! :)
10) V=πr² *h= π*10²*12≈3770
11) V=A(base)*h= (3√3/2)*(9²)*10=2104
A(base)=(P*a)/2=(6*9*3√3)/2=9*9*3√3/2
12)V=πr² *h=π*18² *6≈6107
13)V=4*3*12=144
14) h(triangle)=√(5²-3²)=√16=4
A(base)=(3*4)/2=6
V=A(base)* height (prism)=6*2=12
15) V=A(base)*h= (3√3/2)*(6²)*11= 1029
16)V=A(base)*h=2(1+√2)5²*22≈2656

Answer:
The volume of the solid is 
Step-by-step explanation:
1. Cylinder
For find the volume of a cylinder we use the next formula:

Then the volume of the cylinder is equal to 
2. Cones
For find the volume of a cone we use the next formula:

However there are two cones so we have to multiply the volume of one cone for two and we get the total volume for the cones which is 
3. Sum of the volumes
Finally we sum the volumes of the cylinder and the cones for get the final result

So approximating the result is
