The volume of this sphere is 904.32 cubic inches. What is the surface area of this sphere?
andrew-mc [135]

Answer:

A = 4 pi R^2     V = 4/3 pi R^3

A / V = 3 / R

Also, R = (3 * V / 4 * pi)^1/3 = (3 * 904.32 / (4 * pi))^1/3 = 6 in

So A = 3 / 6 * V = 1/2 * 904.32 = 452.16 in^2

How do I answer this Question? It’s phythagoras theorem!
zhuklara [117]

Answer:

C = 11.18       D= 20

Step-by-step explanation:

Let's start with C

Square root both areas of the squares

\sqrt{25} =5

\sqrt{100}=10

Then use the Pythagoras Theorem: a^{2} +b^{2} =c^{2}

10^{2} +5^{2} =125

\sqrt{125} =11.18033989 = C

Moving on to D

Square root both areas of the squares

\sqrt{841} =29

\sqrt{441} =21

29 is the hypotenuse, we are trying to find the other leg, so:

29^{2} -21^{2} =400

\sqrt{400} =20 = D
