Answer:
perimeter of the fountain = 15π ft. or 47.1 ft. to the nearest 10th
Step-by-step explanation:
The semicircles have a circumference of 1/2πd = 1/2π(10) = 5π
Both semicircles together have a length of 5π + 5π = 10π
The radius of the 1/4 circle is 10, so the diameter is 20
The length of the 1/4 circle's arc is 1/4 times the circumference of its circle
So, the length of that arc is 1/4π(20) = 5π
Now the perimeter of the fountain is 10π + 5π = 15π
The sum of 4 and 8 is equal to 12. In this case, we are asked to determine the number that has the most accurate estimation to the addition of the two numbers. In this case, the answer should be 10. Numbers such as 5, 20 and 25 are really far from 12.
Answer: x/9
Step-by-step explanation: quotient means to divide. X is the unknown number and we divide this by 9.
