Answer:

12

Step-by-step explanation:

nPr=\frac{n!}{(n-r)!}

So in your case, n = 4 and r = 2.

n! = 4! = 4*3*2*1

(n-r)! = (4-2)! = 2! = 2*1

So....

\frac{4*3*2*1}{2*1}=\frac{24}{2}=12

Help I need one more number but I have no clue what it is!!!!!!!!!!!!!
VARVARA [1.3K]

Answer:

The point of intersection with the x axis are (-2,0) and (8,0)

Step-by-step explanation:

given circle equation x²+y² = 25

x² + y² = r²

r is the radius.

✓(25) = 5

given the center is at (3,0) and radius of 5

(3+5,0) and (3-5,0)

(8,0) and (-2,0)

(Please heart the answer if you find it helpful, it's a motivation for me to help more people)

1 A can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10
Ronch [10]

Answer:

radius r = 3 cm

height h = 10 cm

volume V = 282.743339 cm^3

lateral surface area L = 188.495559 cm^2

top surface area T = 28.2743339 cm^2

base surface area B = 28.2743339 cm^2

total surface area A = 245.044227 cm^2

In Terms of Pi π

volume V = 90 π cm3

lateral surface area L = 60 π cm^2

top surface area T = 9 π cm^2

base surface area B = 9 π cm^2

total surface area A = 78 π cm^2

Step-by-step explanation:

Cylinder Formulas in terms of r and h:

Calculate volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**:

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Agenda: r = radius

h = height

V = volume

L = lateral surface area

T = top surface area

B = base surface area

A = total surface area

π = pi = 3.1415926535898

√ = square root
