Answer:

56.25 pi  cm^2

Step-by-step explanation:

To find the area of the circle,

we use the formula

A = pi r^2, where r is the radius

We know the diameter is 15 so we can find the  radius from

r = d/2  where d is the diameter

r = 15/2

A = pi ( 15/2) ^2

A = pi ( 225/4)

A = 56.25 pi  cm^2

Answer:

2nd option

› 56.25π cm²

Step-by-step explanation:

we know ,

area of circle is πr²

so,

given,

diameter,d = 15cm

radius,r = d/2 = 15/2 = 7.5 cm

so,

area = πr²

= (7.5×7.5)π

= 56.25π cm²

i hope you find it helpful !!!!
