.
Answer: the answer is 8.8
Step-by-step explanation: multiply 2.2 by 4
2.2 X 4
Take notes and pay attention since just slacking off for only 10 minutes can get you behind and struggling.
Dr /dt = 7
A = pi r^2
dA / dr = 2pir
dA/dt = dA/dr * dr/dt = 2pir * 7 = 14pir
when r = 12 rate of change of the area = 14*pi*12 = 168pi
= 527.79 cm^2 / minute to nearest hundredth
Answer:
The mixed number 5 1/4 is equal to the improper fraction 21/4.
