Answer:
The shortest walking route is through the diagonal AC: 102.89m
Step-by-step explanation:
One can go from A to C using 2 paths:
- ADC or ABC
- using diagonal AC and half of that inner circle.
We need to compute the length of each path.
1) ADC=AD+DC=80+50=130m
2) AC²=AD²+DC²=80²+50⁵=6400+2500= 8900m²
AC=sqrt(8900)=94.34m.
Note that the diagonal AC has a missing segment, whose length is the diameter of the inner circle. So the straight line has a length of: AC-d=94.34-15=79.34m.
Perimeter of half the circle=pi×r= 3.14×(15/2)= 3.14×7.5=23.55m
So, if one is using the diagonal to go from A to C, then he has to walk:
79.34+23.55=102.89m
Comparing the two routes: 130m vs 102.89m, we notice that the route using the diagonal AC is shorter.
The equation for the volume of a pyramid is (l*w*h)/3
since the problem gave you the base area, that would be the l *w
so now you would need to multiply the base area by the height, then divide by 3
16 * 15 = 240
240/ = 80 cubic centimeters
To find the length of the missing side, subtract all of the known side from the perimeter.
14 + 19 + 25 = 58.
73 - 58 = 15.
The fourth side is 15 feet
