Answer:
<h2>Angle = 72°</h2>
Step-by-step explanation:
To find the length of an arc,
Angle/360 * circumference
Length = 4
Angle = ?
circumference = 20
Angle/360 * 20 = 4
Rearrange to find the Angle.
Angle/360 = 4 / 20 = 0.2
Angle = 360 * 0.2
<h2>Angle = 72°</h2>
Volume of water
=6600 l=6600×0.001m³=6.6m³
▶Considering only inner volume
Let,
x↪ thickness of bottom of cuboid
Then,
↪h=3.5-x
{to get inner height of cuboid}
↪ b=1.2m-2×10cm=1.2m-0.2m=1m
{to get inner breadth of cuboid we must subtract it from 2×thickness of wall }
↪ l=2.4m-2×10cm=2.4m-0.2m=2.2m
{to get inner length of cuboid we must subtract it from 2×thickness of wall }
❇Since
↪inner volume=volume of water
↪ l×b×h=6.6
↪ 2.2×1×(3.5-x)=6.6
↪ 3.5-x=6.6/2.2
↪ x=3.5-3
↪ x=0.5m➡required thickness
Answer:
Less than.
Step-by-step explanation:
Because they have the same denominator, you can ignore them and just look at the numerator. 4 < 6.
