Answer:

72

Step-by-step explanation:

Circumference of a circle = 2πr

Area of a circle: πr^2

Plug in:

C = 2πr

30.1 = 2(3.14)r

30.1 = 6.28r

r = 4.79 (Dividing both sides by 6.28)

Use area of the circle:

A = 3.14(4.79)^2

= 72.044474

Round to nearest whole number = 72

Valentin [98]

The equation that can be used to find the number of points is 9 + (14 × x) = 331 and the value is 23.

<h3>How to illustrate the information?</h3>

From the information, Sonia has completed 14 levels of a video game and has 9 points so far in her current level and she has a total of 331 points.

Let the number of points earned be illustrated as x.

The equation that can be used to find the number of points she earned for completing each level will be:

9 + (14 × x) = 331

9 + 14x = 331

14x = 331 - 9

14x = 322

Divide

x = 322 / 14

x = 23

The number of points is 23.
