The formula for two secants is:
(A+B)*B = (C+D)*D
In the picture :
A = 5
B = 3
C = X
D = 4
(5 +3) * 3 = (X +4)*4
Use distributive property:
24 = 4x + 16
Subtract 16 from both sides:
4x = 8
Divide both sides by 4:
X = 8/4
X = 2

Answer:
1816.7 in³ ≈ 29,769.6 cm³
Step-by-step explanation:
The surface area of a sphere is given by the formula ...
A = 4πr²
Then the radius is ...
r = √(A/4π) = (1/2)√(A/π)
The volume of a sphere is given by the formula ...
V = 4/3πr³
Using the above value of r, we find the volume to be ...
V = (4/3)π(1/2)³(A/π)^(3/2) = 1/6√(A³/π) ≈ 1816.7 in³
__
The answer is requested in cm³. The conversion factor is (2.54 cm/(1 in))³, so this volume is ...
(1816.7 in³)·(2.54 cm/(1 in))³ = 29,769.6 cm³

<em>Additional comment</em>
We suspect an error in the problem statement, as the given units are square inches and the requested volume is in cubic centimeters. Usually, there would be an explicit statement regarding the necessity for units conversion.
Start by finding how many squares in both rooms are. 24 • 15 = 360 and 13 • 4 = 52 (since it is a square room multiply by 4) Now add. 360 + 42 = 412. Now multiply : 6.98 • 412 = 2875.76. The total cost of carpet for both rooms is $2875.76. Hope I helped!
