The complete question in the attached figure
we know that
[area of a circle]=pi*r²
for r=1 unit
[area of a circle]=pi*1²---------> pi units²
if the area a full circle of 360°--------------> is pi
the area of sector 88°------------------------> X
X=88*pi/360--------> 0.77 units²
the answer is
<span> the area of sector AOB is 0.77 units</span>²

<h2>Volume</h2>
The volume of geyser 2 is 768000cm³. if 1000 cm³= 1 litre convert the volume of geyser 2 to liters
- To convert cm to liters divide the volume by 1000
Therefore, 768000 cubic centimeters in liters is 768.
