Yes, the circle's area will change because the radius is different and when you go to do the formula for area the radius will not be the same it will have tripled. The area of the circle with a radius of 3 would be 28.26. The area of the circle with a radius of 1 would be 3.14. The area of a circle with radius 3 is 9 times as big as the area of a circle with radius one. So the answer is 9. Hope that helped.

What is the multiplicative inverse of -27 and what is the multiplicative inverse for 7/9 and -9/16
liberstina [14]

The multiplicative inverse of a number is the number when you multiply it, it gives you the product of 1.

So for - 27, what number will give us 1 when we multiply it by -27

-27 * -1/27 = 1

So the multiplicative inverse of -27 = -1/27

7/9 * 9/7 = 1

-9/16 * -16/9 = 1

So in essence, just take the number and flip it

-27 = -1 / 27

7/9 = 9/7

-9/16 = -16/9

GI bisects DGH so that m DGI is x-3 and mIGH is 2x-13 find the value of x
baherus [9]

x = 10

since GI bisects ∠DGH then ∠DGI = ∠IGH, hence

2x - 13 = x - 3 ( subtract x from both sides )

x - 13 = - 3 ( add 13 to both sides )

x = 10
