If a basketball has a volume of 12,114.7 cm3, what is the distance across of a basketball

1 answer:

4 0

All we need to do is start with the volume formula. Then, input the volume and solve the equation for the radius. And double it to get the diameter.

V = (4/3)pi(r^3)
12114.7 = (4/3)pi(r^3) Divide both sides by (4/3) and pi
2893.64 = r^3 Take the cube root of both sides
14.25 = r

So the diameter is about 28.5 cm (14.25 x 2 = 28.5)

Outline the process for Inscribing an equilateral triangle in a circle. Perform the construction in GeoGebra, and take a

mezya [45]

Answer:

I don't use Geogebra, but the following procedure should work.

Step-by-step explanation:

Construct a circle A with point B on the circumference.

Use the POINT and SEGMENT TOOLS to create a circle with centre B and radius BA.
Use the POINT tool to mark points D and E where the circles intersect.
Use the SEGMENT tool to draw segments from C to D, C to E, and D to E.

You have just created equilateral ∆CDE inscribed in circle A.

A shipping company selects 75 random packages to check their weight.It finds that 3 packages were weighed incorrectly. How many

Misha Larkins [42]

Answer: 120 Packages

Step-by-step explanation:

Given

75 random packages are check

3 package is found faulty

So, the percentage of error is

$\Rightarrow \dfrac{3}{75}\times 100=4\%$

i.e. 4% packages is faulty

For 3000 sample, expected faulty packages are

$\Rightarrow 3000\times \dfrac{4}{100}=120\ \text{Packages}$

Evaluate 23x + 4y when x=20 and y=23

never [62]

Answer:

552

Step-by-step explanation:

23x + 4y when x=20 and y=23

if x=20 and y=23 all you have to do is replace the numbers and solve

23(20) + 4(23)

Multiply 23*20 which is equal to 460

Then you multiply 4*23 which is equal to 92

The problem is now 460 + 92

add it, and you get 552.

Hope this helps!!
