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:
9 notebooks=36 or 12 pens=24+ 4 notebooks=12 in total 36
Step-by-step explanation:
first way: 9×4=36
second way: 12×2=24
3×4=12
24+12=36
Answer:
(0,150)
Step-by-step explanation:
Remember that the y-intercept of a function is where x=0. Therefore, we need to plug in x=0 in the function to get y:
f(x)=150(1.25)^x
f(0)=150(1.25)^0
f(0)=150(1)
f(0)=150
Therefore, the y-intercept of the function is (0,150)
