Answer:
Step-by-step explanation:
The formula of a volume of a sphere:
R - radius
We have R = 3 ?. Substitute
If the radius is 30, then the volume is:
If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:
Answer:
-20 units??
Step-by-step explanation:
Answer:
the length of the missing side is 2
Step-by-step explanation:
Use a^2 + b^2 = c^2
a = 4
b = ?
c = 2sqrt5
4^2 + b^2 = (2sqrt5)^2
16 + b^2 = 20
subtract 16 from both sides
b^2 = 4
take the sqrt of both sides
b = 2
