Meri is making birdhouses. Each birdhouse uses 5 yard of wood. What is the total length of wood Meri will need to make 12 birdhouses?​

Given:

Each birdhouse uses 5 yard of wood.

To find:

The total length of wood Meri will need to make 12 birdhouses.

Solution:

We have,

Required wood for each birdhouse = 5 yards

Now,

Required wood for 12 birdhouses = 12 × 5 yards

                                                        = 60 yards

Therefore, the total length of wood Meri will need to make 12 birdhouses is 60 yards.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
