Outer radius: Ro = 11 m
Inner radius: Ri = 9 m
Area of the sidewalk: A = <span>π (Ro^2 - Ri^2)
A = </span><span>π ( (11 m)^2 - (9 m)^2 )
A= </span><span>π ( 121 m^2 - 81 m^2 )
A = </span><span>π ( 40 m^2 )
A= 40</span><span>π m^2
The exact area of the sidewalk is 40</span><span>π square meters
A = 40 (3.14) m^2
A = 125.6 m^2
The approcimate area of the sidewalk is 125.6 m^2</span>
Answer:
Option d: The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
The data are continuous if they can take on any value within a range. In this case study, there are different elephants including small/young ones and big ones/old ones.
Thus, their heights will vary and can take on any value within a particular range.
Answer:
does this help
Step-by-step explanation:
Add 25 to both sides:
Square root both sides.
When you square root a perfect square, you will get a plus/minus result:
