Question

if r=2.5 cm then, the area of the circle will be​

Answer 1

Answer:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·2.52 = 19.63 square cm(*)

Area of a circle in terms of diameter:

Area = π·(d2)2 = 3.14·(52)2 = 3.14·(2.5)2 = 19.63 square cm(*)

Area of a circle in terms of circumference:

Area = C24π = 15.7124π = 246.8(4·3.14) = 246.812.56 = 19.63 square cm(*)

Answer 2

Answer:

Area of circle= πr^2

Area of circle= 3.14 *2.5 *2.5

= 19.625cm^2
