The formula for the volume of a cylinder is area of the base times the height.
To find the area of the base you must multiply pi times 5 squared (3.14*25=78.5)
Then you must multiply that times the height (78.5*3), which equals 235.5 cubic centimeters

Lets call a to the Alonzo amount of points and m to the Miguel amount of points and write equations out of the problem's info:
a + m = 54
m = a + 4
rearrange:
<span> a + m = 54
</span>-a + m = 4
add the two equations:
<span> a + m = 54
</span><span>-a + m = 4
</span>-----------------
0 + 2m = 58
m = 29
and susbstitute in the first equation:
<span>a + m = 54
</span>a + 29 = 54
a = 54 - 29
a = 25
therefore Alonzo scores 25 points and Mike 29
Solution :
2a + 2b = 7 ...1)
4a + 3b = 12 ...2)
In equation, 1)
a = (7 - 2b)/2 ...3)
Putting value of a in equation 2) we get :
4 × (7 - 2b)/2 + 3b = 12
2( 7 - 2b ) + 3b = 12
14 - 4b + 3b = 12
b = 2
Putting value of b in 3) we get :
a = ( 7 - 2×2)/2
a = 3/2 = 1.5
Now,
2x - 3y = 16 ...5)
x + 2y = -6 ...6)
x = -6 - 2y
Putting above value of x in eq 5) , we get :
2( -6 - 2y ) - 3y = 16
-12 - 4y - 3y = 16
7y = -28
y = -4
x = -6 - ( 2× -4 )
x = 2
Hence, this is the required solution.
If you’re trying to find the area of the step:
A=lwh
A=20•15•8
A=2,400 cubic inches
or 2,400 in ²
