Answer:
2289.06 cm
Step-by-step explanation:
the equation for area of a circle is
Radius is 1/2 the diameter = 27
3.14 (27^2)=2289.06 cm
152 per hour. Just take the 1672 and divide it by 11 to get your rate of change
3+3= 6
6+1= 7 is your answer
To find the slope take two ordered pairs and put them in form of x2-x1/y2-y1 and then you can find the slope.
(-2,17) (-3,20)
(-2)-(-3) = 1
(17)-(20)=-3
slope is 1/-3
