Answer:
Volume = 1539.38 cm³
Surface Area = 747.7 cm²
Step-by-step explanation:
Volume = πr² h
V = π(7)²(10)
V = π(49)(10)
V = 490π
V = 1539.38 cm³
Surface Area = 2πrh + 2πr²
SA = 2π(7)(10) + 2π(7)²
SA = 2π(70) + 2π(49)
SA = 140π + 98π
SA = 238π
SA = 747.7 cm²
Answer:
c:84
Step-by-step explanation:
set your equasion to 9/7 = 108/x .solve the equasion and you get 84 for x
Answer:
6.79
Step-by-step explanation:
First of all, you will have to know how much is 3% of 7 in order to decrease it by that amount.
7 x 0.03 = 0.21
Now that you know the amount, you can subtract it from seven and therefore you have decreased 7 by 3%.
7 - 0.21 = 6.79
Combinations = n! / (n - r)! r!
In this case:
n = 4
r = 3
Combinations = 4! /(4-3)! 3! = 24/(1)(6) = 24/6 = 4

2x + -11 = k
Reorder the terms:
-11 + 2x = k
Solving
-11 + 2x = k
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '11' to each side of the equation.
-11 + 11 + 2x = 11 + k
Combine like terms: -11 + 11 = 0
0 + 2x = 11 + k
2x = 11 + k
Divide each side by '2'.
x = 5.5 + 0.5k
Simplifying
