The mean is the average of all the numbers in the set. To find the average of numbers, you add them all up then divide by how many numbers there are in the set. 5 + 6 + 8 + 3 + 5 + 7 + 4 + 11 + 5 + 7 = 61. 61 divided by 10 = 6.1 The answer is 6.1

Mean = 6.1

Good luck, my guy!

The length of the arc intercepted by a central angle of 3/9 pie is 3.6 feet long. How long is the radius of the circle?

gtnhenbr [62]

Answer:

B) 3.44 feet

The Radius of the circle 'r' = 3.439 ≅3.44 feet

Step-by-step explanation

Step(i):-

Given data the length of arc = 3.6 feet long

l = 3.6 feet

Given central angle 'θ' = $\frac{3}{9} \pi$

Step(ii):-

The arc length 'l' of a circle of radius 'r' with central angle 'θ' radians is given by

Arc length l = r θ

3.6 = r ( $\frac{3}{9} \pi$ )

put π = 3.14

now simplification, we get

$r = \frac{3.6 X9}{3\pi }$

$r = \frac{3.6 X9}{3X3.14 } = \frac{32.4}{9.42} = 3.439$

Conclusion:-

The Radius of the circle 'r' = 3.439 ≅3.44 feet

Area of triangle = 1/2*(6)(8)
Area of triangle = 1/2*48
Area of triangle = 24 sq ft
Area of half circle = 1/2* π*4^2
Area of half circle = 8 π sqft
Area total = 24+8 π
Area total = 49.12 sq ft
