The area of the circle is 452.39 mm².

What is the area of a circle ?

The formula for the area of a circle

A = πr²

where r is the radius, half the diameter.

For the radius is 12 mm. Using that in the formula gives an area of ...

A = π(12 mm)² = 144 π mm²

For an appropriate value of π, the area is

144 π mm²

For 3.14 as the value of π, the area

144 (3.14) mm² = 452.39 mm²

Find the volume of the cylinder.
Either enter an exact answer in terms of
π
πpi or use
3.14
3.143, point, 14 for
π
πpi.

Answers

Answer:

Solution :-

Radius is 3

Height is 2

So,

Volume = πr²h

Volume = 3.14 × (3)² × 2

Volume = 3.14 × 9 × 2

Volume = 3.14 × 18

Volume = 56.5 units²

Answer: 56.52

Step-by-step explanation:

You can get a volume of a cylinder by multiplying pie which is 3.14 by radius squared multiplied the height...

The equation is Volume = πr²h

Or in simpler terms:

3.14 × radius ×radius × height

So the final equation is:

3.14 × 3² × 2

=56.52

How do you find the diameter

Answers

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
