Answer:

100.48 units³

Step-by-step explanation:

Oh not this again, alrighty, so the formula for the area of a cylinder is base x height, so first we have to find the area of the circle:

(the formula for that is pi x radius² and we're just gonna use 3.14 as pi)

2² = 4

3.14 x 4 = 12.56

So now we just have to plug into the formula:

12.56 x 8 = 100.48

So the volume of the cylinder is 100.48 units³

if this is wrong, tell me so I can fix it

hope this helps:)

lubasha [3.4K]

Answer:

<u>1 and 2/3</u>

Step-by-step explanation:

If

length = 1/3     and width= 1/2

then the equation will look like this,

2(1/3+1/2)

1/3+1/2= 5/6

2(5/6)=<u> 1 and 2/3</u>

Two piecewise functions are shown below. What is the value of
gizmo_the_mogwai [7]

Step-by-step explanation:

I am not sure what your problem here is.

you understand the inequality signs ?

anyway, to get

6×f(-2) + 3×g(1)

we can calculate every part of the expression separately, and then combine all the results into one final result.

f(-2)

we look at the definition.

into what category is -2 falling ? the one with x<-2, or the one with x>=-2 ?

is -2 < -2 ? no.

is -2 >= -2 ? yes, because -2 = -2. therefore, it is also >= -2.

so, we have to use

1/3 x³

for x = -2 that is

1/3 × (-2)³ = 1/3 × -8 = -8/3

g(1)

again, we look at the definition.

into what category is 1 falling ? the one with x > 2 ? or the one with x <= 1 ?

is 1 > 2 ? no.

is 1 <= 1 ? yes, because 1=1. therefore it is also <= 1.

so we have to use

2×|x - 1| + 3

for x = 1 we get

2×0 + 3 = 3

6×f(-2) = 6 × -8/3 = 2× -8 = -16

3×g(1) = 3× 3 = 9

and so in total we get

6×f(-2) + 3×g(1) = -16 + 9 = -7
