Question

Hii Stars !!

Solve the above Question,
Given in attachment.​

Answer 1

Step-by-step explanation:

★ Given :-

⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⟹ For Cylinder

⠀⠀⠀⠀⠀⠀⠀⠀

• Height of Cylinder = 28 cm.
• Radius of Cylinder = 3 cm.

⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⟹ For Cone

⠀⠀⠀⠀⠀⠀⠀⠀

• Height of Cone = 10.5 cm.
• Radius of Cone = 3 cm.

⠀⠀⠀⠀⠀⠀⠀⠀

★ To Find :-

⠀⠀⠀⠀⠀⠀⠀⠀

• Volume of the remaining solid.

⠀⠀⠀⠀⠀⠀⠀⠀

★ Solution :-

⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀$\small \maltese \: \bold{V \: of \: Cylinder - 2 × V \: of \: Cone\:\maltese} \\ \\ \small \bold{ = \pi \: {r}^{2} H - 2 \times \frac{1}{3}\pi \: {r}^{2}H } \\ \\ \small\bold{ = \pi \: {r}^{2} \bigg[H - \frac{2}{3} \: H \bigg]} \\ \\ \small\bold{ = \frac{22}{7} \times ( {3}^{2}) \times\bigg[28 - \frac{2}{3 \times 10.5} \bigg] {cm}^{3} } \\ \\ \small \bold{ = \frac{22}{7} \times 9 \times 21 \: {cm}^{3} } \\ \\ \longmapsto \boxed{ \bold \red{594 \: {cm}^{3} }}$

⠀⠀⠀⠀⠀⠀

★ Hence,

⠀⠀⠀⠀⠀⠀

• The Volume of remaining solid = ⠀ $\bold\red{\Rightarrow\:594 \: {cm}^{3}}$

Answer 2

♠︎ We Have To Find :-

• Volume of the remaining solid

♠︎ Given :-

Cylinder

• Height of cylinder = 28 CM
• Radius of cylinder = 3 Cm

Cone

• Height of cone = 10.5 cm
• Radius of cone = 3 cm

♠︎ Solution :-

Volume of cylinder - 2 × Volume of Cone

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎πr2 H - 2 × 1/3 πr² H
