Answer:

12.4

Step-by-step explanation:

The distance between (7,21) and (-5,18)

d =sqrt( (-5-7)^2 + (18-21)^2)

= sqrt(( -12)^2 + (-3)^2)

= sqrt(144+9)

= sqrt(153)

=12.36931688

To the nearest tenth

The points awarded for striking the inner circle ought to be tripled.

What is the inner circle?

The face region of the circle determines the likelihood of landing an outrage there.
The formula for calculating a circle's area is: inner circle for the exterior circle, apply the formula to subtract the inner circle's value to determine the remaining area.

The formula for the area of a(one) circle is an inner circle for the external circle, use the formula also abate the value of the inner circle, to find the remaining area, which means that the area of the external circle is 3( three) times larger, making it 3( three) times more likely to hit the external circle.

Thus, The points awarded for striking the inner circle ought to be tripled.
