The formula is d=C/π.

The diameter is 2 times the radius

The formula for the circumference using the radius is 2πr.

in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.

Therefore, we take out the ÷2 part, which would be 16÷π

16 is the circumference

16÷π=d

d=C÷π

a source of laser light sends rays ab and ac toward two opposite walls of a hall. the light rays strike the walls at points b an

marissa [1.9K]

Let AM be the distance between point A and the right wall and AN be the distance between A and the left wall.
Δ AMB is an isosceles right triangle and Δ ANC is half of an equilateral triangle.
Length of AM = 30 m. Length of AN = 1/2 · 80 = 40 m.
The distance between the walls is:
30 m + 40 m = 70 m.

two angles are complementary. the larger angle is 6 more than five times the number. how large is the smaller angle?

spin [16.1K]

Answer:

14 degrees

Step-by-step explanation:

Complementary angles means they add up to 90 degrees.

If the smaller angle times 5 plus 6 equals the bigger angle, then:

14 x 5 = 70

70 + 6 = 76

76 + 14 = 90
