Answer:
439822.95 cm²
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
True because u can always add or multiply to join groups
Answer:
$3.3
Step-by-step explanation:
To find how much a single cople costs divide 1.1/20=11/200
Then, to find how much money for 60 coples, multiply the amount of money for one cople by 60: (11/200)(60)=
33/10 0r $3.3
Hope this helps! :)
Answer: Perpendicular
Step-by-step explanation: If you graph these points you will get two lines that from at a right angle and cross through each other. This means they are perpindicular.
The answer is 51. This is because if you 15 is added then you multiply by the 10
