Question

Find the radius of a circle if the area is 254.5 com​

Answer 1

radius=2.793304096 or nearly is 2.793

Explanation:

area for circle=pi.(half radius square)

24.5=3.14* (half radius square)

half radius square=7.802547771

after under the half radius square in the root square , then the final answer the radius =2.793304096 or nearly is 2.793

Answer 2

The radius of the circle is approxiamtely 9 cm

Explanation:

Area of a circle =
`\pi`r²

If the area is 245.5 cm²,

therefore, the radius r =
`√(area/\pi )`

taking
`\pi` = 3.143

r =
`√(254.5/3.143)`

r =
`√(80.97)`

r ≈ 9

Therefore, the radius of the circle is approximately 9 cm
