Question

Найдите объём цилиндра с диаметром основания 3 см и высотой 1 см

Answer 1

D=3см  r=d/2=3/2=1.5см  h=1см
V=πr²h
V=3.14*1.5²*1=7.065cм³

Answer 2

Calculating the Volume of a Cylinder

To find the volume of a cylinder, we can use the formula:

Volume = π * (radius)^2 * height

Given that the diameter of the base is 3 cm, we can calculate the radius using the formula:

radius = diameter / 2

Substituting the values into the formula, we get:

radius = 3 cm / 2 = 1.5 cm

Now, we can calculate the volume using the formula for the volume of a cylinder:

Volume = π * (1.5 cm)^2 * 1 cm

Calculating the Volume

Using the given values, the volume of the cylinder is approximately 7.07 cubic centimeters.

This calculation is based on the formula for the volume of a cylinder and the given dimensions of the cylinder's base and height.
