Answer:
Area shaded portion = 16/3 π - 8√3
Step-by-step explanation:
The shaded portion consists of 2 equal segment
∵ Two circles have the same radii = 4
∵ The the length of the common chord of the two circles = 4
∴ The central angle of each segment = π/3 (60° equilateral Δ)
∵ Area segment = area sector - area Δ
∵ Area sector = 1/2 r²Ф = 1/2 × (4)² × π/3 = 8/3 π
∵ Area Δ = 1/4 s² √3 = 1/4 × (4)² × √3 = 4√3
∴ Area segment = 8/3 π - 4√3
∴ Area shaded portion = 2(8/3 π - 4√3) = 16/3 π - 8√3
Answer: 28.26 inches
Step-by-step explanation: C = 2(pie)r or (pie)d
pie rounds to 3.14 the diameter is 9 in. soooooooo. 28.26 in. I don't know if this answer needs to be rounded by there. Have a great day. :)
V = speed of light = 3 x 108 m/s
d = distance = 384000 x 103 m = 3.84 x 108 m
time taken = t = d/V = 3.84 x 108 /(3 x 108 ) = 1.28 sec
3x^2+33x+30=0
3(x^2+11x+10)=0
3(x+10)(x+1)=0
x=-10,-1
One cylinder has two bases and one side, and the side is a rectangle.
So S = 2*base + side
S = 2* (pi*27^2) + (2*pi*27*37) = 3456pi
