We'll be glad to check your answer.
I got 100... i think im wrong! :(
Yep, you're wrong.
Find the folume by following this formula:
V = pi * r^2 * h
V = 3.14 * 4 * 5
V = ?
To find the volume of a right circular cylinder, you can use the formula: V = π * r^2 * h, where V is the volume, π is the mathematical constant pi (approximately equal to 3.14), r is the radius of the base of the cylinder, and h is the height of the cylinder.
In this case, the radius (r) is given as 2 inches and the height (h) is given as 5 inches. Plugging these values into the formula, we have:
V = 3.14 * (2^2) * 5
= 3.14 * 4 * 5
= 3.14 * 20
= 62.8 inches
So, the volume of the can in question is indeed 62.8 cubic inches. Therefore, the statement "the volume of a can (a right circular cylinder) which has a radius of 2 inches and a height of 5 inches has a volume of 62.8 inches (π = 3.14)" is true.
