We know that
the height of cylinder is equal to the diameter of sphere
so
h=2*r------> equation 1
volume of cylinder=pi*r²*h
volume=8 m³
substitute equation 1 in the formula of volume
8=pi*r²*(2*r)------> 8=2*pi*r³-----> equation 2
find the volume of a sphere
volume sphere=(4/3)*pi*r³-----> (2/3)*[2*pi*r³]
substitute the equation 2 in the formula of volume
volume sphere=(2/3)*[8]----> 16/3 m³
the answer is
<span>Yolanda should have found the volume by multiplying 8 by 2/3.</span>
Well if the original number is 10 and now it’s 15 that would make the percentage of increase 0.5%
The pattern here is the number times 3 then plus 1
We can check this by plugging it in.
1×3=3
3+1=4
4 is the next number in our sequence so the pattern works.
We can continue to check this with the rest of our sequence.
4×3=12
12+1=13
13 is the next number in our sequence so the pattern works.
13×3=39
39+1=40
40 is the next number in our sequence so the pattern works.
40×3=120
120+1=121
121 is the next number in our sequence so the pattern works.
We can find the next numbed in the sequence by continuing the patter
121×3=363
363+1=364
So the next number in the sequence is 364
