Given a right cone with radius r and slant height s, what does the formula pi rs represent
2 answers:
<h2>Answer:</h2>
The formula πrs represent the lateral surface area of the cone.
<h2>Step-by-step explanation:</h2>Lateral surface area--
The lateral surface area of a solid ( i.e. a three dimensional object) is the area of all the sides of the solid excluding the area of the base as well as top of the solid.
If r is the radius of the cone and s is the slant height of the cone then the lateral surface area of the cone is given by the formula:

7. None
8. A and D
9. F and G
Step-by-step explanation:
See attachment for complete question
5. B, C and E
B, C and E are not parallelogram because they do not have 2 pairs of parallel sides
B and E are trapeziums while C is just a quadrilateral.
6. C
In (5) above, we established that B and E are trapeziums while C is not. This implies that only C is a quadrilateral.
7. None
A square is a parallelogram. So, it is not possible for a shape to be a square and not be a parallelogram.
8. A and D
A is a rhombus. D is a square and will be treated as a rhombus because all sides are equal.
9. F and G
These shapes have 2 pairs of parallel lines but all 4 sides are not equal; only the opposite sides are equal.
