A thermos in the shape of a cylinder is filled with coffee. The height of the cylinder is 12 inches and its radius is 2 inches.

emmainna [20.7K]

Answer:

Option C is correct

Volume of coffee in the thermos is, 150.8 cubic inches

Step-by-step explanation:

Volume of the cylinder is given by:

$V =\pi r^2h$

Where

V is the volume of the cylinder

r is the radius

h is the height of the cylinder respectively

As per the statement:

A thermos in the shape of a cylinder is filled with coffee.

the height of the cylinder is 12 inches and its radius is 2 inches

⇒ h = 12 inches and r = 2 inches.

Substitute the given values and use $\pi = 3.14$ in [1]

then;

$V =3.14 \cdot 2^2 \cdot 12$

$V =3.14 \cdot 48$

Simplify:

V ≈150.8 inches.

Therefore, the volume of coffee in the thermos is, 150.8 cubic inches
