Question

The circumference of a circle is 17 .6cm find the area of the circle.​

Answer 1

Step-by-step explanation:

circumference = 2πr

17.6 = 2 × π × r

πr = 8.8

r = 2.8 cm

Area = π × r ^ 2

Area = 22 / 7 × 2.8 × 2.8

Area = 24.64 sq.cm

mark me as brainliest...

Answer 2

Answer:

24.6 sq. cm

Step-by-step explanation:

Circumference of a circle is 17.6cm

which translates to

2 π r = 17.6

π r = 17.6/2

π r = 8.8

3.14 * r = 8.8

r=8.8/3.14

r=2.8 cm

Now we have the radius and using which we can calculate the area

Area =  π * r * r

Area = 3.14 * 2.8 * 2.8

Area = 24.6 sq. cm

Another approach would be

A = C^2 / 4π

where C is the circumference

A =( 17.6 * 17.6)/(4 * 3.14)

A = 24.6 sq. cm
