When a circular plate is heated in an oven, its radius increases at the rate of 0.01 cm/min. At what rate is the plate’s area in
m_a_m_a [10]

Answer:

3.14 cm²/min

Step-by-step explanation:

rate of increasing of radius, dr/dt = 0.01 cm/min

r = 50 cm

Area of plate, A = πr²

rate of increase of area

dA/dt = 2πr dr/dt

dA/dt = 2 x 3.14 x 50 x 0.01

dA/dt = 3.14 cm²/min

Thus, the increase of rate of area is 3.14 cm²/min.

Angela earns x dollars an hour. On Friday, she worked 6 hours. On Saturday, she worked 8 hours. Which expression shows how much
makkiz [27]
Each hour she works, she earns x dollars.

The first day, she worked 6 hours, so she'd earn 6x dollars.
The second day, she worked 8, so she'd earn 8x.
Together, she'd have earned 6x+8x dollars.
 You could add the number of hours she worked first and then multiply by x to get the same result. This would look like (6+8)x.
