Answer:
50.24
Step-by-step explanation:
Area = r^2 x 3.14 (pi)
Radius = 8 ÷ 2 = 4
4² = 16
16 x 3.14 = 50.24
Area = 50.24 cm ²
Assuming the frequency be the numbers of people, the greatest number of people should be 8, and they drank 6 glasses.

Complete the math in the brackets (4a + 1)
Multiple each term in the brackets by 4a
4a (8a - 4a + 1)
4a (4a + 1)
16a^2 + 4a
The formula for compounded interest is A = P (1+r/n)^nt.
P=580
r = .09
n = 1
t = 9
