19/4π

45.53 yards

19 x pi 59.690

foot

They both have the same tangent ratio so let the height of the lighthouse be x and change all units into feet: x/216 = 32/19 Multiply both sides by 216: x = 6912/19 x = 363.7894737 feet

The circumference of a circle that has a diameter of 19 is about 59.69

If a circle has a diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)

If a circle is 19 inches in circumference the diameter is: 6.048 inches (circumference divided by Pi = diameter).

The diameter of a circle with a 19 mm circumference is about 6.048 mm (d = c divided by Pi).

It is: 19*pi feet

19/4π

45.53 yards

Circumference = (diameter) times (pi) = 19 pi = 59.69 yards (rounded)

Circumference equals Diameter X Pi. In this case, 19 in X 3.14159 equals 59.69 in.

circumference = pi*19 = 59.6903 cm rounded to 4 dp

It is approx 19 units of length.

If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
