Answer:

Radius = 10.1 m

Circumference = 63.4 m

Step-by-step explanation:

Area = 3.14 × r²

320 = 3.14 × r²

r² = 101.9108280255

r = 10.0950893025

Circumference = 2 × 3.14 × r

= 2 × 3.14 × 10.0950893025

= 63.3971608197

Answer:

10.1 m =r

C = 63.4 m

Step-by-step explanation:

We know the area of a circle is given by

A = pi r^2  where pi can be approximated by 3.14 and r is the radius

320 = 3.14 r^2

Divide each side by 3.14

320/3.14 = 3.14 r^2/3.14

101.910828 = r^2

Take the square root of each side

sqrt(101.910828) =sqrt( r^2)

10.0950893 = r

To the nearest tenth 10.1 =r

Now we want the circumference

C = 2*pi*r

C =2 *3.14 *10.1

C =63.428

To the nearest tenth

C = 63.4

Step-by-step explanation:

Answer choice A is a vertical line through the the x-axis crossing through -3. It has an x-intercept of -3.

Answer choice B is a horizontal line through the y-axis crossing through -3. It has no x-intercpet.

Answer choice C is a horizontal line through the y-axis crossing through 7. It has no x-intercept.

Only A has an x-intercept of -3.
