Answer:
A = 616 cm^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi (14)^2
A = pi (196)
Using 3.14 as an approximation for pi
A = 3.14 *196
A =615.44
The nearest approximation is
A = 616 cm^2
19/30 20/30 21/30 22/30 23/20
36 divided by 3 = 12
3 goes into 36 twelve times.
Okay so the formula for speed is speed = distance divided by time so 120 /4 is 30 for the first bar
