Answer:201 in squared

Step-by-step explanation:

a right circular cone has

a diameter d=8+in ...........r=4+in

a height of h=12+in

the volume

the vomue 1/3 times pie times r squared times height

the vlolume 1/3 times pie times 4 in squared times 12in

the vlolume 1/3 times pie times 16 in squared times 12 in

the vlolume 192 times pie inches squared over 3

the vlolume 200.96 in squared

whcih should equal 201 inches squared.

Answer:12.9 inches

Step-by-step explanation:

V=1/3\pi r²

3V=\pi r² h

h=3V/r²\pi

h=3(488)/(6)²\pi

h=1464/36\pi

h=12.9446...

Which expression(s) have a greatest common factor (GCF) of 3xy2 with 42xy4
Aleks [24]

Answer:

3xy2

Step-by-step explanation:

GCF is the largest  factors which are common in two or more numbers.

We find the GCF of two or more number number by breaking each number into their factor and then observe which factors are common in the group and then we multiple the common number to get the GCF.

Lets understand this by an example

GCF of 24 and 36

factors of 12 = 2*2*2*3  ,   factors of 36 = 2*2*3*3

hence we see that 2,2 and 3 are common in 12 and 36 hence

GCF will be 2*2*3 = 12

Coming back to problem

given

Expression 1 is 3xy^2

factor of 3xy^2 = 3*x*y*y

Expression 2 is 42xy4

factor of 42xy4 = 2*3*7*x*y*y*y*y

common factor between the two expressions are

3, x, y , y

hence GCF will be = 3*x*y*y =3xy2  Answer

Solve the equation or inequality 3/2t-16=4/3t-6
Tamiku [17]

Answer:

<em>t=60</em>

Step-by-step explanation:

3/2t-16=4/3t-6

(subtract 4/3t from both sides)

3/2t-16-4/3t=-6

(add 16 to both sides)

3/2t-4/3t=-6+16

(simplify)

1/6t=10

(divide by 1/6 (or multiply by 6 on both sides)

t=60
