Explain how an estimate helps you place the decimal point when multiplying 3.7 times 5.1

Yuki888 [10]

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

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

The formula for the volume of a right square pyramid is given below, where a is the side length of the base and h is the height.

stira [4]

If it’s v=1/3 *( a^2) * h

Divide both sides by (1/3)*h
v/(1/3*h) = a^2
Or
3v/h = a^2

Square root both sides

Sqrt(3v/h) = a
