how do you do this type of stuff I wanna learn so I can start to help other people
B
the volume (V) of a sphere = πr³
We require to know the radius r to calculate the volume
using surface area of a sphere = 4πr² = 615.752
divide both sides by 4π
r² = = 49.0248...
take the square root of both sides
r = ≈ 7, hence
V= × π × 7³ = 1436.76 m³ → B
Answer:
Step-by-step explanation:
we have the expression:
To factor this expression we need to indentify the components that are common in both terms.
At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:
so we can substitute this into the expression:
and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:
The answer to your question is C
