Answer:
254.47
Step-by-step explanation:
A=πr2=π·92≈254.469
V = s³
v = (1.2s)³
v = 1.728s³
1.728 * 100% = 172.8% increase
Answer
4 and 8
Explanation
List all factors of 32 and then find which number equals 24 when added
Or
You could waste time and use alegbra lol
Step One
Begin by getting one side of the question equal to zero.
32x -4 = 4x^2 + 60 Add - 32x + 4 from both sides.
0 = 4x^2 + 60 - 32x + 4 Collect like terms.
0 = 4x^2 - 32x + 64
Step Two
For this question, you could divide both sides by 4. It just makes the steps later on easier.
0 = x^2 - 8x + 16
Step Three
Calculate the discriminate.
The discriminate is b^2 - 4*a*c
a = 1; b = -8; c = 16
b^2 - 4*a*c = (-8)^2 - 4*(1)(16) = 64 - 64 = 0
There is only 1 root. It is real and it is rational.
