Answer:
The radius of the circle is 12.006 m.
Step-by-step explanation:
Let us assume the radius of the circle = r
Circumference = 75.4 m
Now, CIRCUMFERENCE OF A CIRCLE = 2 π r
⇒ 75 .4 m = 2 π r
Now, putting π = 3.14, we get:
75 .4 m = 2 (3.14) r
⇒ 75.4 = 6. 28 r
or, r = 75.4/6.28 = 12.006
or, r = 12.006 m
Hence, the radius of the circle with circumference 75.4 m is 12.006 m.
Bottom right corner would be the correct answer
sin(θ) = ⁻⁴/₅
sin⁻¹[sin(θ)] = sin⁻¹(⁻⁴/₅)
θ ≈ -53.13
tan(θ) > 0
tan(53.13) > 0
1.33 > 0
