Question

the radius of circle is 1 cm less than half the side of square whose area is 256cm what is the area of the circle​

Answer 1

Answer:

Step-by-step explanation:

The area of the square is 256 square cm.

Let x be the side of square,

X

x^2=256

X=16 cm.

Let r be the radius of circle,which is 1 cm less than half of 16 cm.

That is, r=16/2-1

r=8-1

r=7cm

Therefore, the area of the circle is A=pi(7)^2

A=49pi square cm
