The invest could probably be maybe 8% for a question
The solution would be like
this for this specific problem:
<span>V = ∫ dV </span><span>
<span>= ∫0→2 ∫
0→π/2 ∫ 0→ 2·r·sin(φ) [ r ] dzdφdr </span>
<span>= ∫0→2 ∫
0→π/2 [ r·2·r·sin(φ) - r·0 ] dφdr </span>
<span>= ∫0→2 ∫
0→π/2 [ 2·r²·sin(φ) ] dφdr </span>
<span>= ∫0→2 [
-2·r²·cos(π/2) + 2·r²·cos(0) ] dr </span>
<span>= ∫0→2 [
2·r² ] dr </span>
<span>=
(2/3)·2³ - (2/3)·0³ </span>
<span>= 16/3 </span></span>
So the volume of the
given solid is 16/3. I am hoping that these answers have satisfied
your query and it will be able to help you in your endeavors, and if you would
like, feel free to ask another question.
Answer:
2 2/5
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. First convert the first into the improper fraction -8/5. Now because when dividing fractions you keep the first on, change to multiplication and flip the second equation you have
-8/5 x -3/2=?
Now you just multiply across as you would and normal time multiplying fractions. Remember a negative divided by a negative is a positive! And not after you keep, change, flip and multiply you are left with 24/10. Which is equal to 12/5 but you wanted a mixed number so we convert it into 2 2/5
Answer:
4/663
Step-by-step explanation:
(4/52)×(4/51)
= 4/663
= 0.00603
Answer:
78.5 units
Step-by-step explanation:
To find the area of a circle the formula is πr"2"
First we have to find the diameter the find the radius. We already know that the circumference is 31.4 what we have to do now is work backwards. ( 31.4 / 3.14=10) If the diameter of a circle is 10 the radius is 5. now we just have to follow πr"2" to find the area of a circle. (5"2"= 25 x 3.14= 78.5 units)
