Answer:
<h2>Yes the circumference is about times greater than their diameters</h2>Step-by-step explanation:
We will approach this problem by doing a check
Say the diameter of a circle is 4 cm
Hence the radius is 3 cm
We know that the circumference is
The circumference is about 3 time bigger than the diameter
Let us try another case say the diameter is 6 cm
The radius is 3 cm
Answer:
total area = 99m² + 39.4m²
= 138.4m²
The angular measure L is : 47°
<h3>What are angles?</h3>Angles are formed when two lines meet.
Analysis:
Firstly, we calculate for m using cosine rule.
=
+
-2(510)(820) cos 20
= 260100 + 672400 -83600(0.9396)
= 146618.56
m = = 382.9cm
using sine rule to find ∠L
382.9/sin20 = 820/sinL
sinL = 820sin20/382.9
sinL = 820(0.342)/382.9
sinL = 0.732
L = sin inverse of 0.732 = 47°
In conclusion, ∠L is 47°
