Question

The curved surface area of right circular cylinder oh height 14 cm is 88cm². find the diameter of the base of the cylinder​

Answer 1

Answer:

$\boxed{2 cm}$

Step-by-step explanation:

GIVEN :

• Height of cylinder = 14cm

• CSA of the cylinder = 88cm²

To Find:

Diameter of the base of the cylinder​

Formula:

$\boxed{CSA. of. the .cylinder = 2\pi rh}$    where r is the radius and h is height

Solution:

CSA of the cylinder = 88cm²

⇒ 2πrh  = 88cm²

⇒ 2 × $\frac{22 } {\boxed{7}}$ × r × $\boxed{14}$ =  88

⇒   2 × 22 × r × 2 = 88

⇒88r = 88

⇒r = 88 ÷ 88

⇒$\boxed{r = 1 cm}$

⇔The radius of the base of the cylinder = 1cm

∴  The diameter of the base of the cylinder​ = 2r

                                                                            = 2 × 1

                                                                            =$\boxed{2 cm}$
