Question

Area of sector if its length is 14cm and radius is 10 cm

Answer 1

Answer:Example: find the area of a sector. As established, the only two measurements needed to calculate the area of a sector are its angle and radius. For example, if the angle is 45° and the radius 10 inches, the area is (45 / 360) x 3.14159 x 10 2 = 0.125 x 3.14159 x 100 = 39.27 square inches.

Answer 2

70 cm²

Explanation:

length of arc = 14 cm

r = 10 cm

Here, radius r of an circle and length of the arc (perimeter of the sector) is given. We can find the area of sector by the below mention formula,

`\boxed{\bf Area \ of \ sector = (r)/(2)*length \ of \ arc}`

`\sf = (10)/(2)*14\\\\= 10 * 7\\\\= 70 \ cm^2`
