Dan has started to cover a rectangular floor with tiles. the tiles are twice as long as they are wide. the fllor is 10 1/2 tiles wide and 18 1/2 tiles long. using this pattern, what is the total number of tiles dan will use to cover the floor?

i can you with this answer

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.

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
