Find the surface area of the cylinder formed by the net. Use 3.14 for π.

sineoko [7]

Answer:

138.16 square feet

Step-by-step explanation:

The surface area of the cylinder consists of one rectangle and two circles.

1. The radius of the circle is 4 ft, then the area of the circle is

$A_{circle}=\pi r^2 =\pi \cdot 4^2 =16\pi \ ft^2$

2. The width of the rectangle is 1.5 ft, the length of the rectangle is the circumference of the circle.

Find the circumference:

$C=2\pi r=2\pi \cdot 4=8\pi \ ft$

Hence,

$A_{rectangle}=1.5\cdot 8\pi =12\pi \ ft^2$

3. The surface area of the cylinder is

$SA=2A_{circle}+A_{rectangle}=\\ \\=2\cdot 16\pi +12\pi =32\pi +12\pi =44\pi \approx \\ \\\approx 44\cdot 3.14=138.16\ ft^2$

How do you Multiply Radicals?????

Zolol [24]

Answer:

1. $4\sqrt{5}$

2. $10\sqrt{10}$

Step-by-step explanation:

When you multiply radicals, you do the following

$a\sqrt{b}\cdot c\sqrt{d}\\\\=ac\sqrt{bd}$

with that in mind

$\sqrt{16}\cdot \sqrt{5}$

here we don't need to multiply 16 times 5, because 16 = 4^2 and take the square root of it, gives you 4

$=4\sqrt{5}$

$\sqrt{20}\cdot 5\sqrt{2}\\\\\longrightarrow 20 = 2^2\cdot 5\\\\=2\sqrt{5}\cdot5\sqrt{2}\\\\=(2\cdot5)\sqrt{5\cdot2}\\\\=10\sqrt{10}$
