Question

If the radius of a circle is increased by 16 its area increases by

Answer 1

Answer:

Step-by-step explanation:

Let the radius of Circle A be r. Its area =(pi)r^2.

Next, let the radius of Circle B be 1.16r. Its area =(pi)(1.16r)^2 = 1.3456(pi)r^2.

So the area of Circle B is 1.3456 times that of the area of Circle A.

The area increases by 34.56% on increasing the radius by 16%

Answer 2

Step-by-step explanation:

The area increases by 34.56% on increasing the radius by 16%. What will be the increase in percentage of an area of a circle if its radius is increased by 16(2/3)%? If the radius of a circle is increased by 15 percent, by how much is its area increased? The radius of a circle is increased by 1%.
