<span>26 black cards of out 52
probability that a black card is chosen first = 26/52 = 1/2
</span>there are 13 heart
with replaced
The probability of then drawing a heart is 13/52 = 1/4 then
<span>the probability that a black card is chosen first and a heart is chosen second
= </span>(1/2)(1/4) = 1/8
answer
1/8

1140 + 480 = 1620
Answer:
20.25π
Step-by-step explanation:
The circumference (C) of a circle is calculated using the formula
C = 2πr ← r is the radius
given C = 9π, then
2πr = 9π ( divide both sides by 2π )
r = 
( cancel the π on numerator/denominator )
= 4.5
The area (A) of a circle is calculated using the formula
A = πr² = π × 4.5² = 20.25π
