Step-by-step explanation:
The radius of a cylindrical garden roller is 70 cm and its length is 2 m. How much area will it cover in 5 revolutions?
The formula to solve the above question is given as:
Area covered = Curved surface area × Number of revolutions
Step 1
We find the curved surface area of the cylindrical garden
Area = 2πrh
r = 70cm
h = 2m
Convert height to cm
1m = 100cm
2m = x
Cross Multiply
x = 2 × 100 cm = 200cm
Hence,
Area = 2 × π × 70 × 200
= 87964.59cm²
Step 2
Area covered = Curved surface area × Number of revolutions
= 87964.59cm² × 5 revolutions
= 439822.95 cm²
Answer:
D. 40
Step-by-step explanation:
Interquartile range is the difference between the upper quartile value (Q3) and the lower quartile value (Q1).
In a box plot, Q1 is located at the beginning of the edge of the rectangular box from our left, while the Q3 is located at the end of the edge of the rectangular box to our right.
Interquartile range for City A = 70 - 40 = 30
Interquartile range for City B = 80 - 40
Therefore, city B has greater variability. The interquartile range is 40.
