Answer:

The volume of the cylinder is 9.42ft³

Step-by-step explanation:

radius = half of diameter

r = 2ft /2 = 1ft

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 3ft

π = 3.14

r = radius = 1ft

v = (π * r²) * h

we replace with the known values

v = (3.14 * (1ft)²) * 3ft

v = (3.14 * 1ft²) * 3ft

v = 3.14ft² * 3ft

v = 9.42ft³

The volume of the cylinder is 9.42ft³

(2r - 6)(-5r+4) what is the product

Akimi4 [234]

Answer:

$-10r^{2} +38r-24$

Step-by-step explanation:

Apply FOIL method: $(a+b)(c+d)=ac+ad+bc+bd$

$a=2r,b=-6,c=-5r,d=4$

$=2r(5-r)+2r*4+(-6)(-5r)+(-6)*4$

Apply minus - plus rules

$+(-a)=-a,(-a)(-b)=ab$

$=-2*5rr+2*4r+6*5r-6*4$

Simplify

Multiply $-2*5rr=-10r^{2}$

$=-10r^{2} +2*4r+6*5r-6*4$

Multiply $2*4r=8r$

$=-10r^{2} +8r+6*5r-6*4$

Multiply $6*5r=30r$

$=-10r^{2} +8r+30r-6*4$

Combine like terms

$=-10r^{2} +38r-6*4$

Multiply $-6*4=-24$

$=-10r^{2} +38r-24$

$-10r^{2} +38r-24$

Answer:

The standard deviation of the uniform distribution is:

σ=(b−a)/√12

U(3, 12)

σ = (12−3)/√12 = 9/√12 = 2.5981

U(80, 250)

σ = (250−80)/√12 = 170/√12 = 49.0748

U(4, 93)

σ = (93−4)/√12 = 89/√12 = 25.6921
