0.8 inches
the volume (V) of a sphere is calculated using the formula
V = πr³
change the subject and express in terms of r
multiply both sides by 3
3V = 4πr³ ( divide both sides by 4π )
r³ = 3V / 4π ( take the cube root of both sides )
r = ∛( 3V /4π )
sphere A with V= 40
r = ∛ (120 / 12.56 ) = 2.122
sphere B with V = 10
r = ∛(30 / 12.56 ) = 1.337
sphere A - sphere B = 2.122 - 1.337 = 0.8 inches ( to nearest tenth )
Answer:
5/8
Step-by-step explanation:
So, if we add 7 + 12, then it seems that 19 of the 24 students play one of the two sports. But there are 4 students that play both, so we must account for that.
To get the actual number of students that play sports, we must subtract 4 from 19.
19 - 4 = 15
So now we know that 15 out of the 24 students play sports.
We can divide 15 and 24 by 3 to find the simplified fraction.
15 / 3 = 5 24 / 3 = 8
So 5 out of every 8 students plays one of these sports, which means that the probability of picking one of these students is 5/8!
Pretty much saying 5+ (x*10)_<-25
