If a circle has a circumference of 28.26 units what is the diameter of the circle

Mathematics
1 answer:
stepan [7]2 years ago
5 0

Answer:

The diameter of the circle is 6 units.

Step-by-step explanation:

The circumference formula is Pi*(r^2), so you divide 28.26 by pi (3.14) and get 9. Then here is where the other part of the formula comes, and you get the square root of 9 which is 3. 3 is the radius, and the radius is half of the diameter. 3*2=6.

Identify all solutions for a triangle with A = 38 degrees b = 10, and a= 8. Round to the nearest tenth.
rjkz [21]

Answer:

A = 38°

B = 50.32°

C = 91.68°

a = 8

b = 10

c = 12.77

Step-by-step explanation:

The first thing is to find the angle B, like this:

sin B = b * sin A / a = 10 * sin (38 °) / 8

sin B = 0.77

B = arc sin (0.77)

B = 50.32 °

For angle C, it would be:

C = 180 - 38 - 50.32

C = 91.68 °

Side c, we calculate it like this:

c = a * sin C / sin A = 8 * sin (91.68 °) / sin (38 °)

c = 12.77
