<h3>Explain about the Radius?</h3>

The radius of a circle is the separation between any two points on its circumference. R or r is typically used to indicate it.

The diameter of a circle cuts through the centre whereas the radius extends from the centre to the edges of the circle. The diameter of a circle effectively divides the shape in two.

A circle's area is equal to pi times the radius squared (A = r2). Discover how to apply this formula to determine a circle's area given its diameter.

The radius of a circle is the distance from the center to any point on the edge. The radius is equal to the diameter in half, or 2r=d2 r=d.

V=4 \3πr³

= 4/3 π 9.5³

=3591.36

DIA [1.3K]

Answer:

P(Male or Type B) > P(Male | Type B)

Step-by-step explanation:

Total Female = 85 type A, 12 type B ⇒ 97 Female.

Total Male = 65 type A, 38 type B ⇒ 103 Male

Total type A = 65 + 85 = 150

Total type B = 12 + 38 = 50

total number of people = 97 + 103 = 200

Then the probability would be:

P(Male | Type B) = $\frac{number of male in B}{total number of male}$

= $\frac{38}{103}$

= 0.368

P(Male or Type B) = $\frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}$

= $\frac{103 + (50 - 38)}{200}$

= $\frac{103 + 12}{200}$

= $\frac{115}{200}$

= 0.575

Hence, P(Male or Type B) > P(Male | Type B)

The five members of the Traynor family each buy train tickets. During the train ride, each family member buys a boxed lunch for

larisa [96]

Let's assume

the price of each train ticket is x

we are given

total number of family members =5

so, total cost of ticket = total number of family members*the price of each ticket

so, total cost of ticket =5*x

so, total cost of ticket =5x
