tyrone has a right circular cone whoose hight is 18cm and the radius of whos base is 5sm. the volume if this cone, in cubic cm,rounded to the nearist intiger is
The volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius and h is the height.
In this case, the radius (r) is given as 5 cm and the height (h) is given as 18 cm.
Plugging these values into the formula:
V = (1/3)π(5^2)(18)
V = (1/3)π(25)(18)
V = (1/3)(π)(450)
V ≈ 476.06 cubic cm
Rounding to the nearest integer, the volume of the cone is 476 cubic cm.
To find the volume of a right circular cone, you can use the formula:
V = (1/3) * π * r^2 * h
Where:
V = Volume of the cone
π = Pi (approximately 3.14159)
r = Radius of the base
h = Height of the cone
In this case, the height (h) of the cone is 18 cm and the radius (r) of the base is 5 cm.
So, plugging in these values into the formula:
V = (1/3) * π * (5 cm)^2 * 18 cm
V = (1/3) * π * 25 cm^2 * 18 cm
V = (1/3) * (3.14159) * 25 cm^2 * 18 cm
V ≈ 471.2389 cm^3
Rounding to the nearest integer, the volume of the cone is 471 cubic cm.
To find the volume of a right circular cone, you can use the formula:
Volume = (1/3) * π * r^2 * h
where π is a mathematical constant approximately equal to 3.14159, r is the radius of the base, and h is the height of the cone.
In this case, the height of the cone is given as 18 cm, and the radius of the base is given as 5 cm.
So, to find the volume, substitute these values into the formula:
Volume = (1/3) * π * (5 cm)^2 * (18 cm)
Simplifying this expression:
Volume = (1/3) * 3.14159 * 25 cm^2 * 18 cm
Volume = 0.33333 * 3.14159 * 450 cm^3
Volume ≈ 471.23889815 cm^3
Rounding this volume to the nearest integer, we get:
Volume ≈ 471 cubic cm.
Therefore, the volume of the cone, rounded to the nearest integer, is 471 cubic cm.
