Question:

The circumference of a clock is 22 inches. What is the radius of the clock?

Answer:

Radius = 3.5 inches

Solution:

Shape of the clock is circle.

Circumference of the circle = 2πr

Circumference of a clock = 22 inches

$\Rightarrow2\pi r=22$

$$\Rightarrow2\times\frac{22}{7}\times r=22$

$$\Rightarrow\frac{44}{7}\times r=22$

$$\Rightarrow r=22\times \frac{7}{44}$

$$\Rightarrow r=\frac{7}{2}$

⇒ r = 3.5 inches

Hence the radius of the clock is 3.5 inches.

$d=\dfrac{k_A(T_2-T_1)}{T}\ \ \ \ |multiply\ both\ sides\ by\ T\\\\k_A(T_2-T_1)=dT\ \ \ \ |divide\ both\ sides\ by\ k_A\\\\T_2-T_1=\dfrac{dT}{k_A}\ \ \ \ |subtract\ T_2\ from\ both\ sides\\\\-T_1=\dfrac{dT}{k_A}-T_2\ \ \ \ \ |change\ signs\\\\\boxed{T_1=T_2-\frac{dT}{k_A}}$
