Volume of cylinder = πr²h = π x 4² x 6 = 96π
volume of cone = 1/3πR²H = 1/3π x 8² x 12 = 256π
You can see that volume of cone is more than twice of volume of cylinder. So she is not correct
Answer: (-9,-1)
Step-by-step explanation:
The relation between arc length and exterior angle is given in the figure.
Now we are given far arc length as DE =124
We are given near arc length as BC = 36
So plugging in the formula to find measure of angle A:



Angle A = 44 degrees
Answer : A) 44 degree
The answer is 3.1428 (very close to π actually lol)
First you multiply 4*n and n=3 so 4*3 = 12
then you have 9+12-1
9+12= 21
21-1=20
so your answer would be 20
