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
Circumference = 2 x 3.142 x r
9 = 6.284 x r
9 ÷ 6.284 = r
r = 1.43 cm
Answer:
x^7
Step-by-step explanation:
The quotient rule for exponents states that when exponents with the same base are divided, we can simply subtract the exponents to simplify the expression.
Therefore, x^14 ÷ x^7 = x^(14-7) = x^7
