See the attached figure
radius of the circle = r = 6
the length of one side of the equilateral triangle = L
the height if the triangle = h
The shaded area is the required area.
∴The area = (1/3) (area of circle - area of triangle )
area of circle = π r² = π * 6² = 36 π
An equilateral triangle is inscribed in a circle of radius r
∴ The length of one side of the triangle = √3 * r
= 6√3
and the height of the triangle = (√3 /2) * 6√3 = 9
∴ Area of the triangle = 0.5 * 9 * 6√3 = 27√3
The required area = (1/3) (area of circle - area of triangle )
= (1/3) * ( 36π - 27√3 )
= 12π - 9√3
Answer:
5.7 cm
Step-by-step explanation:
Triangle
Measurements: 9 cm, 14 cm, y cm
14 cm/2= 7 cm
a²+b²=c²
7²+b²=9²
49+b²=81
-49 -49
b²= 32
b= 5.656854249
y= 5.7
Step-by-step explanation:
5x+28x÷4
5x+7x
12x
I hope this helps:)
Answer:
B. 1
Step-by-step explanation:
plz give me brainliest I PROMISE YOU THIS IS CORRECT
12+6=18 18+18=36 total coins.
12 quarters:36 coins.
To simplify divide each side by 12.
12/12=1 36/12=3
The simplified ratio is 1:3.
Therefore the answer is B.
Hope this helps! (:
