Find 1 round
--------------------------------------------------

1 round of the circle = πD
1 round of the circle = π(2x4)
1 round of the circle =8π

--------------------------------------------------
Find 10 rounds
--------------------------------------------------

10 round of the circle = 8π x 10
10 round of the circle = 80π
10 round of the circle = 251.33 m

251.33m. First find the distance around one circle then times by ten for all the circles.
Circumference of each circle=2x(pi)xr
=2(Pi)x10
=25.13
For ten circles=25.13x10
=251.33

What is the square route of 49

7.

One way to figure this out is to go from 2-10, and multiply them by them self each other to see what number works.

Another way is to use a calculator and the square root button.

Hope that helps!

Answer:

First you have to multiply negative four in parentheses, then add minus two

-4×(-8+3x)=32-12x

2+32-12x=34-12x

34-12x=82

-12x=48

x=-4

be rectangular prism and rectangular pyramid have the same volume. determine the value of x, the height of the pyramid.

Marina CMI [18]

ANSWER

$x= 9 \: in$

EXPLANATION

The volume of a rectangular prism is given by the formula,

$V = l \times b \times h$
We substitute the dimensions to obtain,

$V = 6 \times 3 \times 12 \: {in}^{3}$

The volume of the rectangular pyramid is,

$V = \frac{1}{3} \times 6 \times 12 \times x \: {in}^{3}$

Equating the two volumes gives,

$\frac{1}{3} \times 6 \times 12 \times x = 6 \times 3 \times 12$

We divide through by 6×12 to get,

$\frac{x}{3}=3$

We solve for x to obtain,

$x = 3 \times 3$

$x = 9 \: in$
