Answer:
25.12 yds
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
C = 2 * 3.14 * 4
C =25.12 yds
The <em>missing</em> angle is B = 65° and the <em>missing</em> sides are a ≈ 7.461 and c ≈ 6.762.
<h3>How to find all missing sides and angles of the triangle</h3>
In this case, we know two angles (A = 25°, C = 90°) and a side of a triangle (b = 16) and <em>Euclidean</em> properties and the law of the sines must be used to find the rest of variables:
B = 180° - A - C
B = 180° - 25° - 90°
B = 65°
a = 16 × (sin 25°/sin 65°)
a ≈ 7.461
c = 16 × (sin 25°/sin 90°)
c ≈ 6.762
The <em>missing</em> angle is B = 65° and the <em>missing</em> sides are a ≈ 7.461 and c ≈ 6.762.

Step-by-step explanation:
11.3/100*23.3/100*100%
Answer:
a. 81.9
b. 144.7
c. 110.2
d. 48
Step-by-step explanation:
a. 120/109.2 = 90/x
x = 81.9
b. 45.6/120 = 55/x
x = 144.7
c. 304.8/96 = 350/x
x = 110.2
d. 109.2/45.6 = 115/x
x = 48
