The answer is 567.4 π m².
The surface area of the sphere with radius r is: A = 4 π r²The volume of the sphere with radius r is: V = 4/3 π r³
Step 1. Calculate the radius from the volume:V = 4/3 π r³ = 2,254 π m³r³ = (2,254 π) / (4/3 π)r³ = 2,254 π/π * 3/4r³ = 2,254 * 3/4r³ = 1,690.5r = ∛1,690.5r = 11.91 m
Step 2. Calculate the surface area using the r:A = 4 π r²A = 4 π 11.91²A = 567.4 π m²

<h2>Answer:</h2>

The volume of the sphere is = 2254 pi unit^3

The volume of sphere is given by :

\frac{4}{3}\pi r^{3}

2254 pi =\frac{4}{3}\pi r^{3}

r^{3}=\frac{3}{4}*2254

r^{3}=1690.5

r = 11.912

Now, surface area of the sphere is given as : 4\pi r^{2}

= 4\times3.142\times11.912\times11.912

= 1783.34 unit square.

Or if the answer is needed in pi form, then surface area is = 567.58 pi unit square.

An astronaut is working on a satellite 200 miles above the ground. What is the measure of BD⌢, the portion of Earth that the ast
natulia [17]

Answer:

420 miles.

Step-by-step explanation:

You would have to be infinitely far away from a sphere in order to see exactly 50% of its surface all at the same moment. Using simple geometry, you can prove that an observer that is a distance d away from the surface of a sphere with radius R can only see a percent area A of the sphere's surface as given by the equation:

A = 50%/(1+R/d)

Where A is the area seen,

R is the earth's radius 4000 miles

And D is the distance above the earth 200 miles

50% = 0.5 in fraction

Substituting values we have

A = 0.5(1 + 4000/200)

A = 0.5(1 + 20) = 0.5 x 21

A = 10.5%

10.5% of 4000 miles = 420 miles.

Marta_Voda [28]

Answer:

True

Step-by-step explanation:

Considering the above definition of Pooled Variance, the correct answer is TRUE.

This is because Pooled variance is used to determine the reasonable estimates of variance, where several repeated tests are expected at each value.

This helps to provide greater precision estimates of variance.

Fofino [41]
Draw a rectangle with one side equal to 84 in. and the other side equal to 65 in. We know that area = l*w, so the area of the rectangle is 5,460 sq. in. Since Mr. Horn cut the piece of plywood in half, he produces two identical pieces of plywood, with half the amount of area as the original. So, 5,460 sq. in. divided by 2 = 2,730 sq. in.
