Answer:
Perimeter = 317 m
Step-by-step explanation:
Given track is a composite figure having two semicircles and one rectangle.
Perimeter of the given track = Circumference of two semicircles + 2(length of the rectangle)
Circumference of one semicircle = πr [where 'r' = radius of the semicircle]
= 25π
= 25 × 3.14
= 78.5 m
Length of the rectangle = 80 m
Perimeter of the track = 2(78.5) + 2(80)
= 157 + 160
= 317 m
Therefore, perimeter of the track = 317 m
Answer:
66 squares are in the circle.
Answer:
p(win)=0.00094
Step-by-step explanation:
-This is a factorial/combination question.
-The probability is calculated using the formula:
Where:
is the number of successful picks
is the total number of picks
Therefore, we calculate the probability as follows;
Hence, the probability of winning is 0.00094
Answer is B.
the question says that a total of 108 blue shirts and 96 green shirts are sold, so we calculate the total number of shirts in the respective rows, while ensuring that the total number of shirts in the columns add up to 60 small, 86 medium, and 58 large respectively
If you are looking forward to adding them together you will get 145. Just need to know if this questions had options?
