Answer:
904.78
Step-by-step explanation:
we have the radius, which is 6.
were trying to find the volume.
the foemula for the v of a sphere is 4/3(pi)r^3
so, multiply 4/3 times pi and we get 4.18879.
find 6^3, which is 216. multiply tyese two values, and we get 904.77864.
so, the volume of this sphere is around 904.78
Answer:
Solution (4,3)
Step-by-step explanation:
2x-7y= -13
<u>(8x-7y=11)x-1</u>
2x-7y= -13
-8x +7y= -11

x= 4
__________
2x-7y= -13
2(4)-7y=-13
8-7y= -13
subtract 8 from both sides

divide by -7
y= 3
hope it helps..
have a great day!!
Answer:
= 2 4/15 km
Step-by-step explanation:
Speed = 3 2/5 km/hour
The units are not the same. The speeds is in hours and the time is in minutes
Lets convert minutes to hours. 60 minutes = 1 hour
40 minutes * 1 hour/ 60 minutes = 40/60 hours = 2/3 hour
Distance = speed * time
= 3 2/5 * 2/3
Change the mixed number to an improper fraction
3 2/5 = (5*3+2)/5 = 17/5
= 17/5 * 2/3
= 34/ 15 km
Change this back to a mixed number
15 goes into 34 2 times (15*2 = 30) with 4 left over
= 2 4/15 km
Here we have to find GCD of 29 and 63
GCD here is 1
Divide both numerator and denominator by 1
we get (29÷1)/(63÷1)
Answer : Reduced fraction is 29/63
