Answer:
Step-by-step explanation:
Use consistent units. The length of the roller is 2.8 m. The diameter is 168 cm = 1.68 m
Circumference of roller = 1.68π m
Contact area of roller = 1.68π × 2.8 = 4.704π m²
Each rotation levels 4.704π m² of the playground.
Area of playground = 750 rotations × (4.704π m²)/rotation
= 3528π m²
≈ 11,084 m²
Answer:
x = 54
Step-by-step explanation:
The two angles are across a vertex and are therefore equal. Set the two angles equal and solve for x:
2x+2 = 3x - 52
2 = x - 52
54 = x
It's C because 1 and 5 are the same angles so they are parallel.

Answer:
15.500000
Step-by-step explanation:
Change the divisor 0.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
46.5 ÷ 3 = 15.500000
and therefore:
4.65 ÷ 0.3 = 15.500000
Both calculated to 6 decimal places. There, I Solved It For You! :)
