A = pi*r^2
(16/25)*pi = pi*r^2
16/25 = r^2
rt(16/25) = r
r = 4/5
C = 2pi*r
C = 2pi*(4/5)
C = (8/5) pi cm
Answer: 3/100
Step-by-step explanation:
X= grade on next test
Add up all scores, divide by 6 and this equals the average of 84
(86 + 91 + 86 + 61 + 87 + x)/6= 84
add in parentheses
(411 + x)/6= 84
multiply both sides by 6
411 + x= 504
subtract 411 from both sides
x= 93
ANSWER: 93 is needed on the next test to have an average of 84
Hope this helps! :)
