Answer: 800pi inches

=======================================

Explanation:

The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter

We know that the diameter of the wheel is d = 8, so 
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel

One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches

Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move

The number of cubic feet of water in a curved container can be approximated by v = 0.95h2.9. use a calculator to find the amount
Sati [7]
The first thing we must do for this case is to rewrite the expression of the volume correctly.
 We have then:
 v = 0.95 * h ^ 2.9
 Substituting the value of h we have:
 v = 0.95 * (7.5) ^ 2.9
 v = 327.6432831
 round to the nearest tenth:
 v = 327.6 feet ^ 3
 Answer:
 
the amount of water in the container when h = 7.5 feet is:
 
v = 327.6 feet ^ 3

If f(x) = 16x – 30 and g(x) = 14x – 6, for which value of x does (f – g)(x) = 0?
Kay [80]

(f – g)(x) = 0

16x-30 -(14x-6) =0

distribute

16x-30 -14x+6 = 0

combine like terms

2x-24=0

add 24 to each side

2x=24

divide by 2

x=12

Answer: x=12

What is the area of the cross section if the length is 12 cm and the width is 10 cm?
VARVARA [1.3K]

Answer:

120 cm²

Step-by-step explanation:

From the question;

  • Length is 12 cm
  • Width is 10 cm

We are required  to determine the area of the cross section;

  • Note that the cross section is the plane of a solid that remains constant through the solid.
  • In this case, the cross section is a rectangle whose dimensions are 12 cm by 10 cm.

But Area of a rectangle = Length × Width

Therefore;

Area of cross section = 12 cm × 10 cm

                                   = 120 cm²

Thus, area of the cross section is 120 cm²
