Given:

Given that the radius of the cone is 2 inches.

The height of the cone is 4 inches.

We need to determine the volume of the cone.

Volume of the cone:

The volume of the cone can be determined using the formula,

$V=\frac{1}{3} \pi r^2 h$

where r is the radius of the cone and h is the height of the cone.

Substituting r = 2 and h = 4 in the above formula, we get;

$V=\frac{1}{3} (3.14) (2)^2 (4)$

$V=\frac{1}{3} (3.14) (4) (4)$

$V=\frac{1}{3}(50.24)$

V=16.75

Thus, the volume of the cone is 16.75 cubic inches.

A. $-273.15^{\circ}C$

Step-by-step explanation:

We are given that

Sodium gas cooled to a temperature =-78.5 degree Celsius

It takes negative because we are given that temperature below zero

Further sodium gas cooled to a temperature =-194.65 degree Celsius

We have to find the new temperature of the sodium gas.

To find the new temperature of sodium gas we will add the given both temperature values

Now, adding two given values then, we get

The new temperature of sodium gas= $-78.5+(-194.65)=-273.15^{\circ}C$

Hence, the new temperature of sodium gas= $-273.15^{\circ}C$

Option A is true.
