7.5*5=37.5
200/37.5=6
2->72
3->71
4 is the missing x value
8:15
or 8/15
8 out of 15
is found by first, siplifying the radicals in the parenthesis. can be simplified as and stays the same. Now we have to multiply these two by which then results in
Area of pond:
A=
r=1,5m
A=3,142*1,5*1,5=7,0695
Area of pond with path
B=
r=50 cm+1,5m=0,5m+1,5m=2m
B=3,142*2*2=12,568
Area of path:
12,568-7,0695=5,4985=5,50
