The area is a sector of circle that is 1/4 of 14-cm radius circle.
A = 1/4 * pi * r^2
A = 1/4 * 3.14 * (14 cm)^2 = 154 cm^2
A sphere. It is a perfectly circular and even shape, so all cross sections would be circles.
Answer:

Step-by-step explanation:
A coin only has two outcomes. Meaning that she has a 50/50 chance of landing on each side. So, 50% of 20 is 10. According to the theoretical probabilty, the coin would have landed on heads 10 times and tails 10 times. So, for that to be true Maria would have had to land on tails one more time.
