The answer is 41.27cm because the area of the square is 9cm. Then to find the area of the circle you multiply pie times the radius squared which gives you 50.27 so you subtract the squares are from the 50.27 and it gives the shaded par of the circle which is 41.27cm.
Answer:
Step-by-step explanation:
<h2>
<em><u>First</u></em> <em><u> </u></em> <em><u>case</u></em> <em><u>:</u></em> </h2>
Sides of a square = 3 cm
Therefore , area of the square = <em>side × side</em>
= 3cm × 3cm
<h2>
<em><u>Second</u></em> <em><u> </u></em> <em><u>c</u></em> <em><u>ase</u></em> <em><u>:</u></em> </h2>
Radius of the circle = 4cm
Therefore, area of the circle
<h2><em><u>Last</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Area of the shaded region
= <em>Area</em> <em> </em> <em>of</em> <em> </em> <em>the</em> <em> </em> <em>circle</em> <em> </em> <em>-</em> <em> </em> <em>Area</em> <em> </em> <em>of</em> <em> </em> <em>the</em> <em> </em> <em>square</em> <em> </em>

Answer:
The formula of volume of cube is l*b*h
45*25*10=11250 cubic cm
Step-by-step explanation:
volume =length×width ×height
given:
length:45 cm
width:25 cm
height(depth):10 cm
according to the question
45 cm×25cm ×10cm
11250 cubic cm
