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

For a function to be a function there cannot be any x’s repeated. In this case, you’re looking for a function that has an x repeated. The answer is {(1,1),(1,2),(1,3),(1,4)}
C(1;2)
a = 1
b = 2
r = 4
(x-a)² + (y-b)² = r²
(x-1)² + (y-2)² = 4²
(x-1)² + (y-2)² = 16
