Answer:

209.22cm²

Step-by-step explanation:

A=πrl+πr2

l=r2+h2

Solving forA

A=πr(r+h2+r2)=π·4·(4+122+42)≈209.21889cm²

Solve for R<br><br> 3 r + 4 <br> ---------- = 5 <br> 2<br><br> r = ?
lakkis [162]
To find r, first write out the equation:
\frac{3r+4}{2} =5
Next, multiply both sides by 2:
3r+4=10
Now, subtract both sides by 4:
3r = 6
Divide both sides by 3:
r=2

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!

Graph F(x)=32x+2. Please
olga2289 [7]

Answer:

The required graph is shown below:

Step-by-step explanation:

Consider the provided graph f(x)=32x+2

The above function is a linear function.

We can draw the graph of the linear function with the help of two points.

Substitute x = 0 in f(x)=32x+2

f(0)=32(0)+2

f(0)=2

Hence, the coordinates are (0,2)

Substitute f(x) = 0 in f(x)=32x+2

0=32x+2

32x=-2

x=-0.0625

Hence, the coordinates are (-0.0625,0)

Now join the above points.

The required graph is shown below:
