Damien has enough red paint to cover an area, of 36 square meters. the surface area of the playground tunnel he must paint has a radius, r, of 3 meters. the formula for surface area is s = 2πrl where l is the length. solve the formula for l and find the length of the tunnel damien can paint

We will assume the tunnel is a cylinder with radius r = 5 m and length l.

The formula for surface area of the playground tunnel is:

S = 2πrl

S = 2π*5*l

S = 10πl

And we also know that the area of the tunnel is S = 54 m^2 thus we have:

10πl = 54

π = 3.14

10*3.14*l = 54

2.56 is the width of the garden

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
