840 = 1×840=2×420 = 3×280 = 4×210 = 5×168 = 6×140 = 7×120 = 8×105
4220=1×4220 = 2×2110 = 4×1055 = 5×844
2840 = 1×2840 = 2×1420 = 4 × 710 = 5 × 568 = 8 × 355
Answer:
2094.4 cm³
Step-by-step explanation:
The volume of a cone =πr²h/3
Where
r = radius = Diameter/2
Diameter = 20cm, radius = 20cm/2 = 10cm
Height = 20cm
Volume of a cone = π × 10² × 20/3
Volume of a cone = 2094.3951 cm³
Approximately to the nearest tenth = 2094.4 cm³
Therefore , the volume of a cone = 2094.4 cm³
Let x be the total number of papers that need to be delivered.
Number of papers Candy can deliver in 1 minute =x/85
Number of papers Tim can deliver in 1 minute =x/65
Time taken for both Tim and Candy all the papers together =x/ (x/85 +x/65)
= x/ (150x/ 5525)
=221/ 6 minutes
=36 minutes 50 seconds
It takes Tim and Candy 36 Minutes and 50 Seconds to deliver all the papers when they work together.
I hope this helps \(^_^)/
