To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =
π r³
5000πm³ =
π r³
5000m³ =
r³
5000m³ x 3 = 4r³

</span>∛3750 = ∛r³
r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
Answer: 75
Step-by-step explanation:
a*1= 15*5
a= 75
Answer:
340 songs, 17000/50 = 340 lol
Hello,
let's say x is a certain number
10*x+9+2x=633
12x=624
x=52
Proof:
529+104=633
