A pool company is creating an image for a client that has the look of a 3-D image for a family pool and a similar dog pool. find the value of a in the drawing below

As the triangles are similar, the corresponding lines are proportionally equal.

BF = VR

WZ = TM

4 = 12

7= a * crisscross them *

4a = 84

divide bith sides by 4

a=21

(x) - (y) = (1 + 4i)

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a
