Answer:
324π in²
Step-by-step explanation:
The surface area of a sphere = 4πr² ( r is the radius )
Calculate r using the volume (V) formula
V =
πr³
Here V = 972π , thus
πr³ = 972π ( divide both sides by π )
r³ = 972 ( multiply both sides by 3 to clear the fraction )
4r³ = 2916 ( divide both sides by 4 )
r³ = 729 ( take the cube root of both sides )
r =
= 9
Thus
surface area = 4π × 9² = 4π × 81 = 324π in²
X = 3/2 or 1 1/2
Both of the equations equal -10, therefor the equations are equal.
The interest paid for the loan will be:
I=(PRT)/100
P=$749.25
R=12%
T=120 days=120/30=4 months=1/3 years
Hence:
I=(749.25×1/3×12)/100
I=$29.97
The proceeds will be:
Net proceeds=(gross proceeds)-(expenses)
=749.25-29.97
=$719.28
Eleven subtract nine is two; eight adding three is eleven (2,11)
5/2=2 1/2 + 2/5 = 2.9 = 2 9/10
