The area of the shaded sector must be 144π units².
<h3>What is the area of the circle?</h3>
The area of the circle is defined as the product of the pie and the square of the radius.
The area of the circle =
We know that the angle measurement of central angle QRS is less than π radians.
for r = 18 units
The area of the circle = π18² = 324π units²
The area of the half of a circle = 324π /2 = 162π units²
The area of a quarter of a circle = 324π /4 = 81π units²
so
The area of the shaded sector < 162π units²
and
The area of the shaded sector > 81π units²
Hence the answer must be 144π units²

Step-by-step explanation:
- (i) For cuboid shaped container:
- (Given)
- Container is filled with water so the volume of water can be given by the following formula:
- Plugging the values of l, b and h in the above formula, we find:
- (ii) For solid right circular cylinder:
- radius (r) = a cm, h = a cm
- Formula for volume of cylinder is given as:
Answer:
A
Step-by-step explanation:
Metal is stronger than plastic, but it is also much heavier.
The key idea in this paragraph is to highlight how to transport the required materials while reducing the weight as much as possible so orbital velocity can be achieved while breaking through the resistance of the atmosphere.
This statement is the key one because it gives engineers the problem they need to find the answer to make the space exploration a reality.
There are a few ways you could go about this. One way is to use sin 60 to calculate the value of a. In other words, sin 60 = a / 8sqrt(3). Simplifying that you should get a = 12.
So F should be the right answer.
