Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length =
Area of the sector of a circle =
22). Arc length of the circle having central angle =
= 60°
Arc length =
=
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length =
= 12.5π
= 39.27 km
24). Central angle =
=
= 225°
Area of the sector =
= 43.20 yd²
25). Area of the sector =
= 65.97 yd²

Answer:
Step-by-step explanation:
n+21
A. The number of fabric-pattern-color combinations is 4 * 13 * 9 = 468
B. P(1st choice) = no of novels / total books = 3/6 = 1/2
P(2nd choice) = no of remaining novels/ total remaining books = 2/5
P(both novels) = 1/2 * 2/5 = 1/5 (without replacement assumed)
C. P(1st choice) = no of biographies / total books = 2/6 = 1/3
P(2nd choice) = no of remaining biographies/ total remaining books = 1/5
P(both biographies) = 1/3 * 1/5 = 1/15 (without replacement assumed)
D. P(1st choice) = no of history books / total books = 1/6
P(2nd choice) = no of novels/ total remaining books = 3/5
P(a history, then a novel) = 1/6 * 3/5 = 1/10 (without replacement assumed)
