तो ऐसे बना बेलन का आयतन | π r² h | Cylinder volume trick #shorts

If r is the radius and h is height of the cylinder the volume will be (1)/(3)pi^(2)h(b)pi r^(2)h(c)2 pi r(h+r)(d)2 pi rh

The volume of a solid cylinder with height 6 cm is 231 cm^3 . The radius of cylinder is: 6 सेमी ऊंचाई वाले एक ठोस बेलन का आयतन 231 घन सेमी है | इस बेलन की त्रिज्या ज्ञात करें |

If r is the radius of the base and h be the height of a cylinder, then its volume is (………….) cubic units.

Let the area of the base of a cylinder be B and the height of the cylinder be h. Write a formula for the cylinder’s volume V.

Radius of a cylinder is r and the height is h. Find the change in the volume if the height is doubled.

If the total surface area of a cube is 1944 m^2 , then find the volume of the cube : यदि एक घन का पृष्ठ क्षेत्रफल 1944 m^2 है , तो इसका आयतन है :

Radius of a cylinder is r and the height is h. Find the change in the volume if the height remains same and the radius is halved.

Radius of a cylinder is r and the height is h. Find the change in the volume if the height is doubled and the radius is halved.

If h is the height and r is the base radius of an open right circular cylinder of given volume has least surface area, then

The volume of a right circular cylinder is 3 times the volume of a right circular cone. The radius of the cone and the cylinder are 3cm and 6cm respectively. If the height of the cylinder is 1cm, then what is the slant height of the cone? किसी लम्ब वृत्तीय बेलन का आयतन एक लम्ब वृत्तीय शंकु के आयतन से तीन गुना है | शंकु तथा बेलन की त्रिज्या क्रमशः 3 सेमी और 6 सेमी है | यदि बेलन की ऊंचाई 1 सेमी है, तो शंकु की तिर्यक ऊंचाई ज्ञात करें |
