Answer:
8πcm²/sec
Step-by-step explanation:
The radius of the circle increases at a rate of dr/dt = 0.25cm/sec
The radius of the circle r = 16cm
The area of the circle increases at a rate of dA/dt = ?
Area of a circle = πr²
We take the derivative with respect to t
dA/dt = 2πrdr/dt
dA/dt = 2 π (16)(0.25)
dA/dt = 8πcm²/sec
Thank you!!!
Answer:
Slope "m" = (y2 – y1)/(x2 – x1).
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1) or rise over run
Answer:
18 cm = 1.8 decimeters
So 18 cm is more.
Step-by-step explanation:
1 BAG= 4/6 days which is 2/3
4 BAGS= 6 days
? BAGS= 9 days
9 days =2/3 X 9 days
therefore 2 X 3 =6 BAGS
therefore 6bags = 9days
Answer:
- y = x² + 4
- x = √(4-y)
- x² - y = -4
