Step-by-step explanation:
the area of a track ? for a track we would normally look for the circumference. the area here is more that of an ice rink.
anyway, the area is the sum of the area of the rectangle in the middle and the areas of the 2 half-circles at both ends. since the half-circles are equally large, they are together the area of the full circle.
the length of the rectangle is 92.7 m.
the width of the rectangle is 2 times the radius (the diameter) of the circle = 2×31 = 62 m
the area of the rectangle is
92.7 × 62 = 5,747.4 m²
the area of the circle is
pi × r² = pi × 31² = pi × 961 = 3,019.07054... m²
the total area is then
5,747.4 + 3,019.07054... = 8,766.47054... m²
this is rounded to 1 DP
8,766.5 m²

Answer:
Worked 40 hrs in week
Pay $300 for week
Step-by-step explanation:
Hours: 7-11a.m = 4
12-4p.m = 4 So, 4+4=8 hrs per day
So, 8 hrs per day × 5 days a week (8×5)=40
Worked 40 hrs in week
Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300
So, $300 pay for week
Answer:
The relation between is
Step-by-step explanation:
Natural length = 0.23 m
Spring stretches from 23 cm to 33 cm. now
Work done in stretching the spring
where b = 0 & a = 0.1 m
With limits b = 0 & a = 0.1 m
Put the values of limits we get
------- (1)
Now the work done in stretching the spring from 33 cm to 43 cm.
With limits b = 0.1 m to a = 0.2 m
With limits b = 0.1 m to a = 0.2 m
Thus
This is the relation between .
