Question

The area of a circle is 42 pi M squared. what is the area of a 60° sector of this circle​

Answer 1

Answer:

7π square meter

Step-by-step explanation:

We will use the formula for the area of a sector of a circle which is given by:

$Area = \frac { \theta } { 360 ^ { \circ } } \times \pi r^2$

Where $\theta$ is the angle subtended by the sector at the center of the circle. Also, we know that in our case, $\theta=60^{\circ}$.

Substituting the given values in the formula to get:

$A=\frac{60^{\circ}}{360^{\circ}}\times 42\pi =\frac{1}{6}\times 42 \pi =7 \pi$

Therefore, the correct answer is 7π square meter.

Answer 2

Answer:

7π M squared

Step-by-step explanation:

Since a whole circle is 360°, and we need to find 60° of this circle, we are basically wanting to find  $\frac{60}{360}=\frac{1}{6}$th of the circle.

Area is given as 42π M squared, so 1/6th of that is  $\frac{1}{6}*42\pi\\=7\pi$

THus, the area is 7π M squared
