Question

Help!! what is the area of the sector shown in the diagram below?

Answer 1

Option B

The area of sector is 34.2 square centimeter

Solution:

We have to find the area of sector

From given figure in question

Radius = 14 cm

central angle = 20 degrees

The area of sector when angle is given in degrees is given as:

`A=(\theta)/(360) * \pi r^(2)`

Where, "r" is the radius and
`\pi = 3.14`

Substituting the given values,

`A = (20)/(360) * 3.14 * (14)^2\\\\A = (1)/(18) * 3.14 * 196\\\\A = (615.44)/(18)\\\\A = 34.19 \approx 34.2`

Thus area of sector is 34.2 square centimeter
