Answer:
91.14 feet
Step-by-step explanation:
Given:
In a park,a sidewalk is built around the edge of a circular pond.
The sidewalk is 7 feet wide, and the pond measure 15 feet across.
Question asked:
What amount of railing would be needed to go completely around the outer edge of the sidewalk?
Solution:
From distance from one edge of the pond to the another = 15 feet
That means diameter of the pond = 15 feet
And width of the sidewalk = 7 feet all around
combined diameter = 15 + 7 + 7 = 29 feet
Radius,r = 
That means distance between outer edge of the sidewalk to the center of the circular pond = 14.5 feet
Now, we will have to find circumference of outer circular edge of sidewalk:


Therefore, 91.14 feet would be needed to go around the outer edge of the sidewalk.
Answer:
5 and -3
Step-by-step explanation:
x+y =2
X-Y=-8
BY USING SIMULTANEOUS EQUATION
SUBTRACT SUCH THAT
2Y=10
SO Y = 5
X= -3
Answer:
<u>C. 1 to 7.99</u>
Step-by-step explanation:
Let's recall that for calculating the range of a data set, we have to find out the lowest and the highest values of the data set.
As we can see in the graph below, the lowest value in the histogram is 1 and the highest is 7.99, therefore the correct answer is:
<u>C. 1 to 7.99</u>
