Answer:

9 pitchers

Step-by-step explanation:

Given

Cylinder 1:

Radius = r

Height = 9

Cylinder 2:

Radius = 3r

Height = 9

Required

How many pitchers' cylinder 2 can fill

First, we calculate the volume of both cylinders

Volume is calculated as:

Volume = \pi r^2h

For A:

V_A = \pi r^2*9

V_A = 9\pi r^2

For B:

V_B = \pi (3r)^2 * 9

V_B = \pi *9r^2 * 9

V_B = 9* 9\pi r^2

In (a): V_A = 9\pi r^2

So, we have ve:

V_B = 9*V_A

V_B = 9V_A

<em>If the first cylinder can fill 1, then the second can fill 9 pitchers</em>

We will use the Binomial probability formula to find the answer

The formula is given by ⁿCₓ (p)ˣ (1-p)ⁿ-ˣ

We have
n, the number of trial = 16
x, the sample we aim to try = 7
p, the probability of success = 0.5

Substitute these values into the formula

P(7) = ¹⁶C₇ (0.5)⁷ (1-0.5)¹⁶⁻⁷
P(7) = 0.1746 (rounded to four decimal places)

How do I solve this problem? ​
natulia [17]

Step-by-step explanation:

you know the formulas ?

the area of a circle is : pi×r²

the circumference of a circle is : 2×pi×r

with r being the radius, which is half of the diameter.

so, here, r = 10/2 = 5 m

area = pi×r² = pi×5² = pi×25 or 25×pi m²

circumference = 2×pi×r = 2×pi×5 = 10×pi m

for the approximation we make the calculations with pi on the calculator and round to the nearest hundredth.

area = 25×pi ≈ 78.54 m²

circumference = 10×pi ≈ 31.42 m
