A school track is shown the straightaway on each side measures 1,000 meters the curves are semicircles with diameter 74 meters w
1 answer:
Answer:
2232.48 meters
Step-by-step explanation:
From the diagram:
Radius of semicircle = 74
Length of straightway on each side = 1000
The length of school track :
Straightway on each side = 2 * 1000 m = 2000m
Length of semicircle = πr/2
Length of both semicircle = 2 * 3.142 * 74 /2 = 232.47785
Total Length = ( 2000 + 232.47785) = 2232.48 meters

Answer:
Step-by-step explanation:
Given : A biologist studied how cells grow by adding liquid protein to cell samples.
She divided of an ounce of liquid protein evenly among 3 cell samples.
Here , total quantity of liquid protein = of an ounce
Total cell samples = 3
Now , Quantity of liquid protein given by her to each cell = (total quantity of liquid protein ) ÷ (3)
= .
Hence, Quantity of liquid protein given by her to each cell =
