Question

Find the area of a sector of a circle with radius 12 cm and the angle of the
sector 30.
Plz plz asap​

Answer 1

Given :-

• Radius of the given circle = 12cm

• The angle of the sector = 30°

To Find :-

The area of sector?

Solution :-

Here, we have to find the area of sector

Radius = 12cm , Angle of sector = 30°

Therefore,

We know that,

Area of sector = Φ/360° * πr²

Subsitute the required values

Area of sector

= 30°/360° * 22/7 * 12 * 12

= 3/36 * 22/7 * 12 * 12

= 1/12 * 22/7 * 12 * 12

= 22/7 * 12

= 264/7

= 37.71cm²

Hence, The area of the given sector is 37.71cm² $.$

Answer 2

Given:-

• Radius of the circle is 12 cm.
• The angle of the sector is 30°.

⠀

To Find:-

• The area of sector.

⠀

Solution:-

According to the question,

⠀

⇢ Φ/360° × πr²

⇢ 30°/360° × 22/7 × 12 × 12

⇢ 3/36 × 22/7 × 12 × 12

⇢ 1/12 × 22/7 × 12 × 12

⇢ 22/7 × 12

⇢ 264/7

⇢ 37.71 cm²

⠀

Hence,

• The area of the given sector is 37.71cm².
