Here, we have: A(r) = 4πr²
We need to calculate it for r = 6,
A(6) = 4π(6)²
A(6) = 4π(36)
A(6) = 144π
In short, Your Answer would be Option D
Hope this helps!
it just says hi answer as fast as you where is the question
The first answer is that the system represents 2 lines. They are two parallel lines.
For the second question, it just represents 1 line. In this case, the two lines are right on top of each other. This is because they are the same equation, just in different forms.
If 1 cup of chocolate chips weighs about 6 ounces
The recipe calls for 3 1/4 cups of chocolate chips.
We need to multiply 6 by 3 which is 18 ounces plus the 1/4 which is 6 times 1/4 = 1.5 ounces
18 + 1.5 = 19.5 ounces of chocolate chip needed
