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>
Answer:
150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.
Step-by-step explanation:
Since ratio of two numbers is 5 : 8 ,
lets assume two numbers be 5x and 8x.
Difference of two numbers = 8x - 5x = 90
⇒3x =90
⇒x = 90/3=30
so two numbers are 5x = 5 × 30 = 150 and 8x = 8 × 30 = 240
Hence 150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.

Step-by-step explanation:
Answer:A reta é um objeto unidimensional, isto é, possui apenas uma dimensão. Observando bem uma reta, é possível notar que qualquer medida feita sobre ela representará apenas um comprimento. Dessa maneira, pode-se afirmar que retas não possuem largura, apenas comprimento.
