What is the angular diameter to the nearest hundredth of a degree of a
spherical object with a diameter of 16 m at a distance of 1338 m?
O 0.09 degrees
6.28 degrees
O 0.21 degrees
O
1.24 degrees
O 0.69 degrees

Answer 1

Answer:
`0.69\°`

Step-by-step explanation:

The angular diameter
`\delta` of a spherical object is given by the following formula:

`\delta=2 sin^(-1)((d)/(2D))`

Where:

`d=16 m` is the actual diameter

`D=1338 m` is the distance to the spherical object

Hence:

`\delta=2 sin^(-1)((16 m)/(2(1338 m)))`

`\delta=0.685\° \approx 0.69\°` This is the angular diameter
