Question

What is the radius of the largest circle that can be cut out of the rectangle measuring $10\mathrm{cm}$ in length and $8\mathrm{cm}$ in breadth?

• A. $4\mathrm{cm}$
• B. $5\mathrm{cm}$
• C. $8\mathrm{cm}$
• D. $10\mathrm{cm}$

Answer 1

The correct option is A

$4\mathrm{cm}$

The explanation for correct option:

Find the radius of the largest circle,

Given that,

The rectangle's largest circle, measuring $10\mathrm{cm}$ in length and $8\mathrm{cm}$ in width, can be cut out.

The diameter of circle is $8\mathrm{cm}$

Then,

$$\begin{gathered} \mathrm{Radius}=\frac{\mathrm{Diameter}}{2} \\ =\frac{8}{2} \\ =4\mathrm{cm} \end{gathered}$$

Hence, Option (A) is the correct answer.
