Answer:
197.92 cm
Step-by-step explanation:
The formula to find volume for a cylinder is V=πr^{2}h
The problem gave you the height (h): 7cm and the radius (r): 3cm and pi (π) is a constant that will automatically insert when you use the "π" button in a calculator
Now that you know that you have all your variables, you can now plug them into your formula.
V=π3^{2}7
Next, solve the equation.
V=π(9)(7)
V=π(63)
V=197.92cm
Hope this helped! :)
Substitute the y=1:
2x + 5(1) = 9
2x + 5 = 5
subtract the 5:
2x = 4
Divide by 2:
x = 2
Answer: 2×2=4
Step-by-step explanation: 2 is a prime number so you can do 2×2
The answer is option c. Thank you
They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
<span>5x3 − 6x4
</span>So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you : )
