The diameter of a cylinder is 3yd the height is 8yd

Mathematics
1 answer:
nalin [4]3 years ago

Answer:

volume= 56.55 yds

Step-by-step explanation:

If you're looking for the volume, the formula is V=\pi r^{2} h.

Diameter is two times the radius (radius is half of the diameter) so the radius of the cylinder would be 1.5 yds.

After you've gotten that information, plug those values into the formula.

V=\pi 1.5^{2} 8

Solve 1.5^2 first. Then multiply that value by pi. Then multiply that value by the height which is 8yds.

Volume=56.55yds rounded to the nearest hunderedth.

Find the product and fill in the blanks to write in standard complex number form
k0ka [10]
X^2 +2x +10 = 0

D = 4 -40 = - 36 

x_1,2 = (-2 +/- sqrt(-36))/2 = (-2 +/- 6i)/2 = 2(-1 +/- 3i)/2 = -1 +/- 3i 

x_1,2 = -1 +/- 3i   or more understandably 

x_1 = -1 -3i and x_2 = -1 +3i

Problem 37

<h3>Answer: B. 4 & 1/4 gallons</h3>

-------------------

Work Shown:

The 3/4 and 1/2 add up to (3/4)+(1/2) = (3/4)+(2/4) = 5/4 = 1&1/4

The whole part 1 is then added to the other whole parts 1 and 2 to get 1+2+1 = 4

Overall, the grand total is 4 & 1/4

An alternative way is to convert each mixed number to a decimal to get 1&1/2 = 1+1/2 = 1+0.5 = 1.5 and 2&3/4 = 2+3/4 = 2+0.75 = 2.75

Add up those decimals 1.5+2.75 = 4.25

then convert that result to a mixed number: 4.25 = 4+0.25 = 4+1/4 = 4&1/4

================================================

Problem 38

<h3>Answer: C. Cubic feet</h3>

----------------

The units for volume follow the template "Cubic _____" where you'll write "feet", "inches", "centimeters" or whatever unit you are using in the blank.

Some other examples:

* cubic miles

* cubic meters

* cubic yards
