67.67 where the first one was the best in my opinion I was a bit confused when it came out of my mind that it is
Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
Answer:
$496, 000
Step-by-step explanation:
2021 is 11 years since 2010, hence t = 11
Substitute t = 11 into the equation
p = (1.95 × 11²) + (12.25 × 11) + 125
= 235.95 + 134.75 + 125
= 495.7 ( thousands of dollars ), thus the best estimate is
p = $ 496, 000
