I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.

The surface area is calculated based on the surfaces which are visible from the outside. In this case, you only need to calculate the surface of lateral side on the cone, the surface of lateral side on the cylinder, and the circle on the lower base of cylinder.

Write the expression to find the surface area
sa = lateral side of cone + lateral side of cylinder + circle
sa = (π × r × s) + (2 × π × r × t) + (π × r²)

Input the numbers
sa = (π × 1 × 3) + (2 × π × 1 × 2) + (π × 1²)
sa = 3π + 4π + π
sa = 8π
sa = 8 × 3.14
sa = 25.12

to the nearest tenth
sa = 25.1

The surface area of the composite solid round is 25.1 m²

If (44)x = 432, what is the value of x?
Gemiola [76]

Answer:

x= 9.81... repeating

Step-by-step explanation:

Divide 44 to isolate x.

(44)x = 432

x= 432/44

x= 9.818

Or if you want a fraction,

x= 108/11

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give
Darina [25.2K]

Answer:

x-ey=e+e^2

Step-by-step-explanation:

We are given that  

y=lnx

Point (e,e)

We have to find the equation of tangent line to the given graph.

Differentiate w.r.t x

\frac{dy}{dx}=\frac{1}{x}

By using formula

\frac{d(lnx)}{dx}=\frac{1}{x}

Substitute x=e  

m=\frac{dy}{dx}=\frac{1}{e}

m=\frac{dy}{dx}=\frac{1}{e}

Slope-point form:

y-y_1=m(x-x_1)

x_1=e,y_1=e

By using this formula  

The equation of tangent to the given graph  

y-e=\frac{1}{e}(x-e)

ey-e^2=x-e

x-ey=e+e^2
