Answer:
21.5%
Step-by-step explanation:
The area of the 4 circles together = 4×π×12^2
The area of the square = 48^2
then the probability that the point is in one of the circles =
(4×π×12^2)÷48^2
=0.785398163397
Therefore, the probability that the point is not in a circle =
1 - 0.785398163397 = 0.214601836603
converted into percentage : 21.4601836603
rounded = 21.5%
Answer:
the answer is b.
a little tip is if your between to answers and for exanple a and b pick b because d and b are more used for answers than a and c.
Step-by-step explanation:
Answer
Work:
Volume is total = 8460 in3
Width 40in
Height 9in
Length?
Formula v/(w x h)
40 x 9 = 360
8460 / 360 = 24in
Length is 23.5 in

From the above equation, we get
cosθ=sinθ
Hence
θ=450
Therefore
sin4θ+cos4θ
=sin4450+cos4450
=2×(21)4
=2×41
=21
Volume: 2112.5π
Surface Area: 663π
First, let's find the height of the cylinder. Using the formula for lateral surface area, 2*π*r*h:
2*π*13*h = 325π
(divide π by both sides)
26h = 325
h = 12.5 in.
Next, let's solve the surface area of the cylinder using the formula π*r²*h.
π * 13² * 12.5 = π * 169 * 12.5 = 2112.5π.
Next, let's solve the surface area using the formula 2πrh + 2πr².
(2 * π * 13 * 12.5) + (2 * π * 13²) = 325π + 338π = 663π.
