\huge{\underline{\underline{\sf{\red{Required\:Solution:-}}}}}

<h3>Volume of cylinder B is greater.</h3>

<h2>For Cylinder A :-</h2>

\displaystyle{\sf{\:\:\:\:\:\:\:\:r(radius)\:=\: \dfrac{7}{2}cm}}

\displaystyle{\sf{\:\:\:\:\:\:\:\:h(height)\:=\: 14cm}}

\displaystyle{\boxed{\sf{ Volume\:=\: \pi r^{2}h}}}

Substitute the values and simplify it

\displaystyle{\sf{\:\:\:\:\:\:\:\:\:\:= \dfrac{22}{7} \times \bigg(\frac{7}{2}^{2} \bigg)\times14}}

\large{\boxed{\sf{\orange{= 539 cm^{3}}}}}

<h2>For Cylinder B:-</h2>

\displaystyle{\sf{\:\:\:\:\:\:\:\:r(radius)\:=\: \dfrac{14}{2}cm=7cm}}

\displaystyle{\sf{\:\:\:\:\:\:\:\:h(height)\:=\: 7cm}}

\displaystyle{\boxed{\sf{ Volume\:=\: \pi r^{2}h}}}

Substitute the values and simplify it.

\displaystyle{\sf{\:\:\:\:\:\:\:\:\:\:= \dfrac{22}{7} \times (7^{2})\times7}}

\large{\boxed{\sf{\green{= 1078 cm^{3}}}}}

<h3>By actual calculation of volumes of both the cylinders, it is verified that the volumes of cylinder B is greater.</h3>

Q2. A train travels at a constant speed of 45 m/s. a) Calculate the distance travelled by the train in:
alex41 [277]

Answer:

i) 1350 m

ii) 5400 m

Step-by-step explanation:

<u>Formula for Speed</u>

\boxed{\sf Speed=\dfrac{Distance}{Time}}

Rearrange the formula so that Distance is the subject:

\implies \sf Distance = Speed \times Time

<h3><u>Question (i)</u></h3>

Given:

  • Speed = 45 m/s (meters per second)
  • Time = 30 seconds

Substitute the given values into the formula for distance:

\implies \sf Distance = 45 \times 30 = 1350\:m

<h3><u>Question (ii)</u></h3>

Given:

  • Speed = 45 m/s (meters per second)
  • Time = 2 minutes

As the time is given in a different unit of time as the speed, we must first convert the time into seconds:

1 minute = 60 seconds

⇒ 2 minutes = 60 × 2 = 120 seconds

Therefore:

  • Speed = 45 m/s (meters per second)
  • Time = 120 seconds

Substitute the values into the formula for distance:

\implies \sf Distance = 45 \times 120 = 5400\:m
