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

Find the radius of the circle containing 60° arc of a circle whose length is 14 m.

Sauron [17]

Given:

It is given that

$\begin{gathered} \theta\text{ = 60}^0 \\ Arc\text{ length = 14}\pi \end{gathered}$

Required:

The radius of the circle

Explanation:

The length of an arc is given by the formula,

$\begin{gathered} Arc\text{ length = }\frac{\theta}{360}\text{ }\times\text{ 2}\pi r \\ \end{gathered}$

Substituting the values in the formula,

$\begin{gathered} 14\pi\text{ = }\frac{60}{360}\text{ }\times\text{ 2}\times\pi\times r \\ r\text{ = }\frac{14\times360}{60\times2} \\ r\text{ = }\frac{5040}{120} \\ r\text{ = 42} \end{gathered}$

Answer:

Thus the radius of the circle is 42 m.
