Find the Volume of the cylinder​
JulsSmile [24]

\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}}

The area of a square is increasing at a rate of 24 centimeters squared per second. Find the rate of change of the side of the sq
velikii [3]

Answer:

3cm/s

Step-by-step explanation:

Area of a square is expressed as:

A = L²

Rate of change of area is expressed as:

dA/dt = dA/dL•dL/dt

Given that

dA/dt = 24cm²/s

L = 4cm

Required

dL/dt

Since dA/dl = 2L

dA/dl = 2(4)

dA/dl = 8cm

Subatitute the given values into the formula

24 = 8 dL/dt

dL/dt = 24/8

dL/dt = 3cm/s
