Question

can some one please help me?

Answer 1

Answer:

56.25 cm^2

Solution,

Circumference of circle=15 pi cm

Radius=?

Now,

Circumference of circle=2pi r

or,15=2*pi*r

or,15=2r*pi

or,r=15/2 pi

r=7.5 pi

Again,

area of circle=pi r ^2

=pi*(7.5)^2

=56.25 pi cm^2

hope it helps

Good luck on your assignment

Answer 2

Answer :56.25 cm^2

Circumference of circle=15 pi cm

Radius= unkown

so....

Circumference of circle=2pi r

r=7.5 pi

Next ....

=pi*(7.5)^2

=56.25 pi cm^2
