Step-by-step explanation:
2.5/6 = h/9
h/9 =2.5/6
h = 2.5 * 9 /6 = 2.5*3 / 2 = 7.5/2 = 3.75
Answer:
squares of each side 1 m makes a square of side. 5 km. Solution: 2,50, ... Area of school playground is 160 m × 80 m = 12800 m2 ... Area of circular garden with diameter 8 m is.
Step-by-step explanation:
look it is a long process
first use sine rule
u will get the other side
then u will find angle X as sum of all angles is 180 so u gotta subtract...
A of trianngle=1/2(a x b) sin(angle X)
ANS=337.13 = 340

Step-by-step explanation:
i see a sector hosting 2 semi circles.
this sector area will be .25 of area of circle with radius 4ft.
area of sector = .25*π*16= 4π ft^2
area of semi circle of radius 2ft = .5π*4= 2πft^2
area of 2 semicircles = 4π
the total area of sector = area of 2 semicircles - intersection area + area not covered by semi circles
4π = 4π - intersection area+area not covered by semi circles
intersection area = area not covered by semi circles
now draw a square starting from the intersection point of 2 semi circles at their upper portion. the side will be 2ft
the area of intersection will be covered in the square.
area of intersection = 2*quarter area of circle of radius 2ft - area of square
= 2*(.25π4) - 4
2π-4 = 2.28
area of intersection = area not covered by semicircle
so area of shaded region = 4.56
