Radius would be 16 in. (2x8 in.). Circumference would be approximately 50.27 in. (16 x pi, which is approximately 3.1416).
For a cylinder the formula is: V = radius2 x Pi x length. So,32 x 3.14 x 8 = 226.08 cubic inches
No but nearly
136 in.
No triangle can have 4 sides of measurements
11.5819 square meters (rounded)
Radius = Diameter/2. So in this case, radius = 8in/2 = 4 in
4 inches The radius of a circle is always half of its diameter (so 8in/2 = 4 in).
The radius is half the diameter. So d/2=r8/2= 4Radius of a diameter that is 8in would be 4 inches.
19.63 square inches.
how do you measure diameter
The surface area of a cylinder that has a radius of 6 in and height of 8in is 527.8 square inches.
The area of a circle can be found with the formula (pi)r2. Since r = d/2, r would be 8in in this case. A = 64pi in2, or 201.1in2
50.26 cm2
V = 1,608.5 cubic inches.
the formula to start off with is the circumference is pi x diameter therefore re-arranging the formula the diameter is the circumference divided by pi diameter = circumference / pi = 18ft 8in / 3.1415 = 5ft and 11 inches to the nearest inch (to be more precice to diameter is 5ft 11.3 inches--- note it is more difficult to work in feet and inches and easier to work in metres and centimetres)
You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.
Volume = pi*82*15 = 3015.929 cubic inches (rounded)
