Answer:
6
Step-by-step explanation:
(n- 1)(n)( n +1)=210
n(n²-1)=210
n³-n= 210
n³-n-210=0
let n = 6 => 6³-6-210 = 216-6-210 = 0 (true)
so, n = 6
Area of small circle = PI x r^2
r = 1/2 the diameter ( 1/2 * 3 = 1.5)
3.14 x 1.5^2 = 7.065 square cm
there are 2 small circles so total area for them = 7.065 * 2 = 14.13 square cm
the area for the large circle = PI x r^2
the radius of the large circle is 3 cm
3.14 x 3^2 = 28.26 square cm
the area of the shaded area is: 28.26 - 14.13 = 14.13 square cm, which can round down to 14 square cm.
Answer:
(A) 0.08
Step-by-step explanation:
P(A) = 0.8
P(B) = 0.1
P(A and B)
= 0.8 x 0.1
= 0.08
