A circle with a radius of 1/2 ft is dilated by a scale factor of 8. Which statements about the new circle are true? Check all th

AfilCa [17]

The circle is being dilated by a factor of 8 so the radius will be 8 times the original radius (4 ft).

The circumference of a circle = $2\pi r$ , so if r is replaced by $8r$ we get $C = 2\pi * 8r$ or just $C = 8*(2\pi r)$ .

Basically the circumference will be 8 times the original circumference.

If you plug in the original radius, into this new formula you get $C_{new} = 8*(2\pi * \frac{1}{2}) = 8\pi \: ft$

The area of a circle = $\pi r^2$ , so if r is replaced by $8r$ we get $A = \pi*(8r)^2$ or just $A = 64\pi r^2$

Basically the area will be 64 times the original area.

If you plug in the original radius into this new formula you get $A = 64\pi * (\frac{1}{2})^2 = 16\pi \: ft^2$

The answers are A, C, F, G, and H
