1. Which one of the following lines has the smallest slope?
A. y=+6
B. y = 2x + 10
C. y = 51-1
D. 5y = 15x + +
E. 7y = 3x - 7

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

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.
