Area of a circle = PI x r^2
you state pi = 3.19 ( it is usually 3.14, if it is a typo see below )
diameter = 14cm
r = 1/2 the diameter, so r = 7 cm
area = 3.19 x 7^2
area = 3.19 x 49 = 156.31 square cm
( if PI = 3.14, area = 3.14 * 49 = 153.86 square cm)
Answer:
2/8 more per day
Step-by-step explanation:
3/8 (new daily amount) - 1/8 (old daily amount) = 2/8 (or 1/4) which is the amount due to the new cat
A=95.2
because 6.8 x 14=95.2
and 95.2/14 is 6.8
