Answer:
<em>2,143.6in³</em>
Step-by-step explanation:
The beach ball is spherical in nature;
Volume of the ball = 4/3πr³ where;
r is the radius of the ball = 8in
Substitute into the formula;
Volume of the ball = 4/3π(8)³
Volume of the ball = 4/3π(512)
Volume of the ball = 2,048(3.14)/3
Volume of the ball = 2,143.57in³
<em>hence the volume of the ball is 2,143.6in³</em>
For area, just multiply the length x width
So therefore, multiply 36 inches x 48 inches and there you have it.
Now for the perimeter, it is a little different
You'd have to add the sides up together to get your answer for the perimeter.
So, 36 in + 36 in + 48 in + 48 in = answer

The librarian could use 3 and 18 as a factor pair
<h3>How to determine the factor pair</h3>
The number of books is given as:
n = 54
Express 54 as a product of two numbers
54 = (1, 54), (2, 27),(3, 18) and (6, 9).
From the options, we have the following factor pair
3 and 18
Hence, the librarian could use 3 and 18 as a factor pair

Answer:
B. y = 1.5x +8
Step-by-step explanation:
You can try x=4 in the various equations to see which gives the right value (14).
__
A: y = -8(4) +1.5 = -30.5
B: y = 1.5(4) +8 = 14 . . . . . . . . . this equation works
C: y = 8(4) +1.5 = 33.5
D: y = -1.5(4) +8 = 2
__
Alternatively, you can use the 2-point form of the equation of a line to write the equation:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (20 -14)/(8 -4)(x -4) +14 . . . . fill in (x1, y1) = (4, 14); (x2, y2) = (8, 20)
y = 1.5(x -4) +14 . . . . . simplify somewhat
y = 1.5x +8 . . . . . . . . write in slope-intercept form
