So because 25%=1/4 we would know to multiply 9*4
Which would get our answer to be 36 :)
To determine how much of the wall is blue we first need to find its area. The wall is a rectangle, then its area is the product of its height and length:

Hence, the area of the wall is 140 square ft. To determine how much of the wall is already painted we multiply this by 1/2, then:

Therefore, 70 square ft are blue.
V=1/3(pi)(r)^2(h)
V=1/3(pi)(9)^2(15)
V=1/3(3.14)(81)(15)
Then multiply all numbers in parentheses:
3815.1/3=1271.7 cm^3
Hope this Helps!
