r = √(3V/πh)
multiply both sides by 3 to eliminate the fraction
πr²h = 3V ( divide both sides by πh )
r² = 3V/ πh ( take the square root of both sides )
r = √(3V/πh)
Answer:
2x+3x+4=6
Step-by-step explanation:
You'd plug in the y-equation which is y=3x+4 into the placement of the y in the first equation 2x+y=6,
Which would then result in 2x+3x+4=6, which is the answer
All you have to do is divide the number by the denominator which is 8. So 510 divided by 8.
Which will give you 63.75.
Then you times it by the numerator which is 3 so 63.75 x 3
And you are left with £191.25 which is 3/8 of 510
It is the first answer choice because a negative times a negative is a positive.
