F(r) = 3.14r^2....and ur looking for f(5)....so basically all u do is sub in 5 for r.
f(5) = 3.14 * 5^2
f(5) = 3.14 * 25
f(5) = 78.50 <===
THE ANSWER IS 78.50
Answer:
a) cannot be determined
b) a triangle can be drawn, but its dimensions cannot be determined
Step-by-step explanation:
<h3>a)</h3>
The vertical axis is labeled in units of kilometers. The horizontal axis is labeled as distance, with no units given. The line shown appears to descend from 12 units above ground level over a distance of 34 units along ground level. One could argue the slope is 12/34 = 6/17, but there is no indication the horizontal units are the same as the vertical units.
The slope of the graph cannot be determined, because we don't know the horizontal units.

<h3>b)</h3>
You can draw the triangle, but you cannot determine its dimensions.
Answer: 8 miles
Step-by-step explanation:
24/3=8
Answer: the slope is the rise over run of the line on a grid so the amount it takes for a point to go up and over
