Answer:
<u><em>True, the diameter=2in and the circumference=6.28</em></u>
Step-by-step explanation:
The circumference, C, of a circle is found by the following equation: C = 2 x pi x r where r equals the radius of the circle (or half its diameter) and pi = 3.14159 (a constant).
Thus, 6.28 = 2 x pi x r
Solving for r: 6.28/(2 x pi) = r
or: 6.28/(2 x 3.14) = 6.28/6.28 = r
thus r = 1 and since the diameter equals 2 x r, the diameter is 2.
Answer:
38.1 ft²
Step-by-step explanation:
The area of the given triangle is computed using the formula ...
area = 1/2sin(A)bc
= 1/2sin(60°)(11 ft)(8 ft) ≈ 38.1 ft²
