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

Luke has 1/3 of a package of dried apricots. He divides the dried apricots equally into 3 small bags. Luke gives one of the bags

Nitella [24]

1/3 ÷ 3 = $\frac{1}{9}$ for each

Luke will stay with a total of:

$\frac{1}{9}$ (x 3) = $\frac{3}{9}$

$\frac{3}{9} - \frac{1}{9} = \frac{2}{9}$

Hope it helped!
