Question

the perimeter of a circular plate is 132 cm find the area​

Answer 1

Answer

perimeter of circle(circumference)=132

π(2r) = 132

r = 132/2π

r = 66π = 207.2

area of circle = πr²

area = 3.14×207.2×207.2

area ≅ 134805

Answer 2

Answer:

1387.38 cm²

Step-by-step explanation:

Perimeter of a circle = 2 π r

132 = 2 π r

132 = 2 * 3.14 * r

132 = 6.28 * r

r = 132 / 6.28

r = 21.02 cm

Area of a circle = π r² = 3.14 * 21.02 * 21.02 = 1387.38 cm²

So, the area of the circular plate is 1387.38 cm²
