Answer:
16x^2
Step-by-step explanation:
(4x)^2
This can be rewritten as
(4x)*(4x)
4*4 *x*x
x*x is the same as x^2
16 x^2
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
Answer:
3x + 3 = -2x + 3
3x + 2x = 3 - 3
5x = 0
x =0.
So y = 3(0) + 3 = 3.
