Answer:
The radius of the sphere is 7m
Step-by-step explanation:
Given
Volume of a sphere = 1372π/3 m³
Required
The radius.
The volume of a sphere is calculated using the following formula.
V = 4/3 πr³
Where V = volume of the sphere and r represents it's radius.
By substitution;
1372π/3 = 4/3 πr³
Multiply both sides by 3
1372π = 4πr³
Divide through by 4
343π = πr³
Divide through by π
343 = r³
Take cube root of both sides.
r = 7.
Hence, the radius of the sphere is 7m
Answer:
$12,750
Step-by-step explanation:
The price at purchase = 3000 dollars
Sale = 325 percent increase in purchase price.
325% = 3.25
3.25x3000 = 9750 dollars
So, at 325 percent increase in price, this painting sold for $9750.
The retail price of this painting =
Price at purchase + price during sale
= 3000 + 9750
= $12,750
Therefore the retail price is equal to $12,750
Answer: 3 cm
Work Shown:
(1 cm)/(5 m) = (x cm)/(15 m)
1/5 = x/15
1*15 = 5*x ... cross multiply
15 = 5x
5x = 15
x = 15/5
x = 3
The model is 3 cm tall.
