A round barbecue pit is 2 meters in diameter. What is the distance around the barbecue pit? A) 12.56 meters. B) 18.84 meters. C)

Pani-rosa [81]

The formula for circumference is 2×pi × r

We are given the diameter of 2 meters which means the radius is 1 meter. We will use 3.14 for pi.

2 × pi × r =
2 (3.14)(1) =
6.28

The distance around the barbecue pit is

C. 6.28 meters

Approximately how many times as great is the volume of a grapefruit with a diameter 16 cm as the volume of a lime with a diamete

SIZIF [17.4K]

Answer: The volume of the grapefruit is approximately 8 times as great as the volume of the lime.

Step-by-step explanation:

You need to use the formula for calculate the volume of a sphere. This is:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

<u>Volume of the grapefruit</u>

You know that its diameter is 16 centimeters.

Since the radius is half the diameter, you get that its volume is:

$V_g=\frac{4}{3}\pi (\frac{16\ cm}{2}) ^3\\\\V_g= 2,144.66\ cm^3$

<u> Volume of the lime</u>

According to the information given in the exercise, the diameter of the lime is 8 centimeters.

As it was explained above, the radius is half the diameter. Knowing that, you get that volume of the lime is the shown below:

$V_l=\frac{4}{3}\pi (\frac{8\ cm}{2}) ^3\\\\V_l= 268.08\ cm^3$

In order to find approximately how many times as great is the volume of theat grapefruit as the volume of that lime, you need to divide the volumes calculated above. Then:

$\frac{2,144.66\ cm^3}{268.08\ cm^3}\approx8\ times$

2/3x -3.2 = -8.1 please help

andriy [413]

Answer:

x = -7 - 17/20 or -157/20

Step-by-step explanation:

2x/3 - 3.2 = -8.1

2x - 9.6 = -24.3

20x - 96 = -243

20x = -157

x = -157/20

x = -7 - 17/20
