Answer:
The area of the shaded region is 148.04 cm².
Step-by-step explanation:
It is provided that a 7 cm × 5 cm rectangle is inside a circle with radius 6 cm.
The sides of the rectangle are:
l = 7 cm
b = 6 cm.
The radius of the circle is, r = 6 cm.
Compute the area of the shaded region as follows:
Area of the shaded region = Area of rectangle - Area of circle
Thus, the area of the shaded region is 148.04 cm².
The volume of a sphere is given by the equation , where V is the volume and r is the radius.
To answer this question, simply plug the correct values into the equation:
The volume of the air in the balloon is about 113.0976 in3.
