What is the mean number of points scored be these players? A. 7 B. 8 C. 9 D. 10

2 answers:

6 0

The answer would be 10. You add all of the numbers together then divid by the amount of numbers there are. For example 6+10+9+11=40. Because there are 4 numbers, you divid 40 by 4 to get 10:) hope this helps!

A porch has the shape of a semicircle with a diameter of 7 ft.

Komok [63]

A = pi * r^2

R = D / 2

R = 7 / 2

R = 3.5

A = 3.14 * 3.5^2

A = 3.14 * 12.25

A = 38.465

Divide it by 2 since its a semi-circle:

38.465 / 2 = 19.2325

So about 19 square feet.
