The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V
Nat2105 [25]

Corrected Question

The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V(5/7) represent?

Answer:

(B)the volume of the rubber ball when the radius equals five-sevenths feet

Step-by-step explanation:

The Volume of a sphere of radius r can be found using the formula:

V(r)=\dfrac43 \pi r^3

Therefore comparing the expression: V(\dfrac57)  with V(r):

Radius, r=\dfrac57

Thus, V(\dfrac57)  is the volume of a ball of radius \dfrac57 feet.

The correct option is B.

Explain how you find it
aliina [53]

Answer:

x = 39

Step-by-step explanation:

there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two

so, (36 + 42)/2 = x

36 + 42 = 78

78/2 = 39

Solve for x<br> -2x + 4 = 6x - 12
aleksklad [387]

Answer:

x=2

Step-by-step explanation:

-2x+4=6x-12  Add 2x to both sides.

<u>+2x    +2x</u>

4=8x-12         Add 12 to both sides.

<u>+12  +12</u>

16=8x            Divide by 8 on both sides.

<u>/8 /8</u>

2=x

Hope this helps you out and have a great day (~^▽^)~

A circle has a diameter of 6 centimeters what is the approximate area of the circle​
KiRa [710]

Answer:

28.26 cm^{2}

Step-by-step explanation:

The radius is half of the diameter. 6/2 = 3, so the radius of this circle is 3 cm.

The formula for the area of a circle is: πr^{2}

Plugging 3 into the radius, we have:

3^{2} × π =

9 × π

We can round π to 3.14

9 × 3.14 = 28.26
