Answer & Step-by-step explanation:
The ratio of square feet to gallons of paint:
This can also be written as:
This fraction can be simplified by dividing the numerator and denominator by 6:
So, the ratio of square feet to gallons of paint is:
1 gallon for every 240 ft².

ball is filled with 350 cubic inches of air, how
much more air is needed to fill it completely?
Round to the nearest whole number.
Answer:
32 cubic inches of air are needed to fill it completely.
Step-by-step explanation:
A basketball has the format of a sphere.
The volume of a sphere with radius r is given by the following equation:
In this question:
Radius of 4.5 inches. So the volume, in cubic inches, is:
The volume of the ball is 382 cubic inches.
350 cubic inches have already been filled.
So 382-350 = 32 cubic inches of air are needed to fill it completely.
A.16
B.64
C.256
D.none of these
Answer:
64π in²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
where r is the radius.
The radius of a circle is half the diameter. For the circle shown, the radius is ...
r = d/2 = (16 in)/2 = 8 in
Then the area is ...
A = π(8 in)² = 64π in²
