∙ 13y agoThe volume of a cylinder is pi*(radius)^2*height. We are not given the radius here, but we know the circumference. Circumference is 2*pi*radius. So radius is equal to the circumference/(2*pi). We can then substitute this into the equation for volume to get: V=pi*(circumference/(2*pi))^2*height=(circumference)^2/(4*pi)*height._________________________________________________________________For your problem we have circumference=84 inches and height=32 inches. So:(84 inches)^2/(4*pi)*32 inches=7056 square inches/(4*pi)*32 inches=1764 square inches/pi*32 inches=56448 cubic inches/pi=17967.9564553 cubic inches which is about 17968 cubic inches.
V=4/3 pi r cubed=113 cubic inches
Circumference is a linear measure and has no volume - just as a straight line has no volume.
Radius = 23.565/(2*3.142) = 3.75 inches Volume = 4/3*3.142*3.753 = 220.921875 cubic inches Surface area = 4*3.142*3.752 = 176.7375 square inches
Circumference = 48 = 2*pi*r inches so radius = 48/(2*pi) = 24/pi = 7.64 in Also, height = 7 ft = 12*7 = 84 inches Then volume = pi*r2*h = pi*(7.64)2*8 = 15401 cubic inches, approx or 8.91 cu ft.

14.52 inches (rounded)
V=4/3 pi r cubed=113 cubic inches
Remember the circle eq'n C = pi d Algebraically rearrange d = C / pi Hence C = 19/3.141952.... C = 6.047887837... inches.
17.9 cubic feet.
i got 10.82 inches.. might wanna check it though
To determine the cubic inches of a ball when you only know the circumference, you first need to find the radius by dividing the circumference by 2π. Then, you can use the formula for the volume of a sphere, V = 4/3 πr³, where r is the radius that you calculated.
Circumference is a linear measure and has no volume - just as a straight line has no volume.
Earth's diameter is approximately 501 684 480 inches; its circumference is approximately 1 577 727 360 inches; its volume is approximately 8.457 × 1022 cubic inches.
Radius = 23.565/(2*3.142) = 3.75 inches Volume = 4/3*3.142*3.753 = 220.921875 cubic inches Surface area = 4*3.142*3.752 = 176.7375 square inches
The density of a baseball is the mass of the ball divided by its volume. The average density will be around 1000 kg/m^3. (Meters cubed)
Circumference = 48 = 2*pi*r inches so radius = 48/(2*pi) = 24/pi = 7.64 in Also, height = 7 ft = 12*7 = 84 inches Then volume = pi*r2*h = pi*(7.64)2*8 = 15401 cubic inches, approx or 8.91 cu ft.
