4 variables turned into 1/3

explanation

Consider one variable as an Independent and give some value and substitute in every

equation, then get new equations in only 3 equations in 3 unknows, if the three

equations have unique solution or no solution. if the equations have unique solution

then the system of given four equations in 3 unknows has infinity solutions (one for every

independent variable value) or

no solution (if the rank of the augmented matrix is not same as the rank of the matrix)

i saw this question before, dont know the asnwer srry

step-by-step explanation:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
