Question

helllloooo.


solve this question to be brainlist.
I need a quality answer. thanks to be here.^_^(^^)^_^and good night.

Answer 1

given radius of the bigger circle 9 cm

its area become πr²

3.14×81=254.34 cm²

and another circle that cut has radius 4cm

3.41×16

=50.24 cm²


remaining area be

254.34 - 50.24 cm²

= 204.12 cm²

hope it help you dear

Answer 2

Given radius of metal sheet = 9 cm.

Given that circle of radius 4 cm is removed.

Now,

Area of circular sheet = πr^2

= > (3.14) * (9)^2

= > 254.34cm^2.

(2) Area of removed part = πr^2

= > (3.14)(4)^2

= > 50.24cm^2.

Hence,

The area of remaining sheet = 254.34 - 50.24

= > 204.1cm^2.

Therefore, the area of remaining sheet = 204.1cm^2.

Hope it helps!
