Answer:
Our radius is already given, 8.
8 x 3.14 x 2 = 50.24cm <-------- perimeter/circumference
8^2 x 3.14
64 x 3.14 = 200.96cm2 <------- area
Formula of a circumference:
2πr
2 x pie x radius (pie can be used as 22/7 or 3/4 most likely 3.14)
Formula of an area of a Circle:
πr^2
pie x radius squared (pie can be used as 22/7 or 3.14)
5cm
13^2-12^2=25
C^2 = 25
C = 5
The value of the probability P(3≤x<7) is 1
<h3>How to evaluate the probability expression?</h3>
The expression is given as: P(3≤x<7)
This is calculated using:
P(3 ≤ x < 7) = P(3) + P(4) + P(5) + P(6)
Using the figure of the probability density function (see attachment), we have:
P(3 ≤ x < 7) = 0.30 + 0.30 + 0.20 + 0.20
Evaluate
P(3 ≤ x < 7) = 1
Hence, the value of the expression is 1

Answer:
2.5
Step-by-step explanation:
5/8 ÷ 1/4
Division sign changes to multiplication and the reciprocal of the divisior is used to multiply instead :
5/8 * 4/1
= (5*4) / (8*1)
= 20 / 8
= 2.5
