Answer:

Radius: 7.75; Volume: 142 (rounded to 3 s.f.)

Step-by-step explanation:

The vollyball is a sphere.

The diameter of a sphere is twice as much as its radius.

Radius = 15.5 ÷ 2

           = 7.75

The volume of a sphere is \frac{3}{4} \pir² where r is the radius.

Volume =  \frac{3}{4} \pi(7.75)²

             = 45.046875\pi

             = 142 (rounded to 3 s.f.)

Which is a characteristic of the line that passes through the points (6, 10) and (12, 7)?
mihalych1998 [28]

Answer:

Step-by-step explanation:

The general formula of the linear equation is:

y = mx + c 

where m is the slope and c is the y-intercept

1- getting the slope:

We are given the two points:

(6,10) representing (x1 , y1)

(12,7) representing (x2 , y2)

The slope of the line will be calculated as follows:

m = (y2-y1) / (x2-x1) = (7-10) / (12-6) = -3/6 = -0.5

The equation of the line now becomes:

y = -0.5x + c

2- getting the value of the y-intercept:

To get the value of the y-intercept (c), we will use any of the given points, substitute in the equation of the line and solve for c. I will use the point (6,10) as follows:

y = -0.5x + c

10 = -0.5(6) + c

10 = -3 + c

c = 13

Based on the above, the equation of the line would be:

y = -0.5x + 13

Hope this helps :)
