Answer:
0.51cm/s
Step-by-step explanation:
Area of a circle A = πr²
r is the radius
Rate of change of area is expressed as;
dA/dt = dA/dr • dr/dt
dA/dr = 2πr
radius r = 77cm
dA/dt = 79cm²
Get dr/dt
Substitute the given values into the formula
79 = 2π(77)•dr/dt
79 = 154dr/dt
dr/dt = 79/154
dr/dt = 0.51cm/s
Hence the rate of change of the radius is 0.51cm/s
Answer:
Replace one equation with the sum/difference of both equations and Yes
Step-by-step explanation:
In Khan Academy
I think it would be 55 only because line P is 145 degrees so because line S is straight it is 90 degrees. So you would subtract the two (145-90) and would come up to B or 55.
