The volume of the spherical dome will be 12.9π cubic feet when the surface area of the dome is 13.924π.
<h3>What is the volume of the sphere?</h3>
The volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. The dome is the shape of a semi-sphere the volume of the dome will be half of the volume of the sphere.
Given that the Reunion Tower in Dallas, Texas, is topped by a spherical dome that has a surface area of approximately 13,924π square feet.
The volume of the dome will be calculated as below:-
SA = 13.924π
2πr² = 13.92π
r = √6.96
r = 2.63 feet
Volume = 2 / 3 πr³
Volume = ( 2 / 3 ) π ( 2.63)³
Volume = 12.24π cubic feet
Therefore, the volume of the spherical dome will be 12.9π cubic feet.

Answer:
b = -23/16
Step-by-step explanation:
The variable x can be eliminated from the system by multiplying the first equation by -2 and adding that to the second equation.
-2(-4b +x) +(8b +2x) = -2(7) +(-9)
16b = -23 . . . . . collect terms
b = -23/16 . . . . divide by the coefficient of b
The value of b is -23/16 = -1 7/16.
Answer: The temperature will be 36.4 degrees.
Step-by-step explanation:
Hi, to answer this question we have to subtract the product of the temperature decrease per week (-1.3) and the number of weeks (12) to the actual temperature (52).
Mathematically speaking:
52 - (1.3 x 12)
Solving:
52-15.6
36.4 degrees
The temperature will be 36.4 degrees.
