A circle has a radius of 11.6 in. If the area is multiplied by 16, what happens to the circumference?

Circumference is times 4

Step-by-step explanation:

Area is proportional to r²

Area is times 16

Radius is times 4

Since circumference is 2pi×r, it's proportional to r

So circumference is also times 4

Circumference: 2 × pi × (4×11.6)

92.8pi in

It will be 4 times larger

Step-by-step explanation:

The formula for circumference is

C = 2 * pi *r

The formula for area is

A = pi * r^2

If the area is increased by 16, we will call the new radius b

16A = pi b^2

Divide this equation by the old equation for area

16A =       pi b^2

A              pi r^2

Canceling

16 = (b/r)^2

Taking the square root of each side

4 = b/r

Multiplying by r on each side

4r = b

The radius increased by 4 times, or the radius is 4 times larger

This will mean that the circumference is 4 times larger

the answer is d. (1.2, -4.7) on edgn

hope this !

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
