Which of the following formulas would find the lateral area of a right cone where r is the radius and s is slant height?
2 answers:
For a right circular cone, the lateral surface area is given by,
The value of square root of h²+r² is equal to slant height s.
So replacing the value of square root of (h²+r²) by s in the formula for lateral surface area , we have
L.S.A. = pi * r * s
where s is slant height of the given right cone.
Answer: The lateral surface area of a right cone is pi*r*s.
Option C is the correct answer.

Answer:
0.60 > 0.50
Step-by-step explanation:
Given
Required
Represent using decimal number and compare
From the question, we understand that there are 100th grids;
So:
Comparing both decimals;
Since 0.60 is greater than 0.50, we have:
0.60 > 0.50
Answer:
Step-by-step explanation:
If ' n ' is the cardinal number of a set, the number of subsets of a given set can be obtained by using the formula 2ⁿ
Given,
N = { 1 , 42 , 65 , 12 , 31 , 27 }
where n ( total number of elements ) = 6
So, the number of possible subsets of set N :
= 2ⁿ
= 2⁶
= 2 × 2 × 2 × 2 × 2 × 2
= 64
