Question

Find the perimeter of the given
sector of a circle.​

Answer 1

Answer:

11 units

Step-by-step explanation:

Perimeter is radius×theta

So,

Theta=π/3

So,

Perimeter=

22/7×10.5/3

33/3

11units

Answer 2

Step-by-step explanation:

(FYI, I AM USING ¢ IN PLACE OF THETA)

we know that the area of sector of a circle= ¢/360° × (πr^2)

therefore, according to question,

area = 60°/360° × (22/7 × 10.5 ×10.5)

area= 1/6 × 22× 1.5×10.5

area = 1/6 × 346.5

area = 57.65 square units.

hence, the area of given sector of circle is 57.65 square units
