Answer:5
Step-by-step explanation:
Because the circumference of a circle is the diameter times 3.14, all you have to do to get the diamater is reverse it and divide the circumference by 3.14
Answer:
30°
Step-by-step explanation:
Area of a triangle can be found using either of the formula:
1. area = 1/2 x base x height
2. area = 1/2 ab sin c
Since we know the length of the two edges, we will use the 2nd formula:
Area = 1/2 ab sin c
Substituting the known values:
28 = 1/2 (14)(8) sin c
28 = 56 sin c
sin c = 0.5
c = 30°
