What is the radius of right circular cylinder?
What is the radius of right circular cylinder?
Solution: Since, internal radius = 8 cm π r = 8 cm, thickness of the wall of the cylinder = 2 cm. ∴ Its external radius = 8 cm + 2 cm = 10 cm i.e., R = 10 cm. Also, length (height) of the cylinder = 42 cm i.e., h = 42 cm.
What is the formula of total surface area of right circular cylinder?
The general formula for the total surface area of a cylinder is T. S. A. =2πrh+2πr2 .
How do you draw a right circular cylinder?
- Step 1: Let the given height of the cylinder be h and radius of the base be r.
- Step 2: Calculate the circumference of the base of the required cylinder as 2πr.
- Step 3: From the chart paper cut out a rectangle ABCD having lengths 2πr and breadth h (see Figure 38.1).
What is the curved surface area of right circular cone?
Right Circular Cone Formula For a right circular cone of radius ‘r’, height ‘h’ and slant height ‘l’, we have; Curved surface area of right circular cone = π r l. Total surface area of a right circular cone = π(r + l) r. Volume of a right circular cone = 1/3π r2 h.
What is the volume of a right circular cylinder whose base area is 606 cm2?
Answer Expert Verified = 121200 cm sq.
What is formula of CSA of Cone?
Curved surface area of a cone = \pi rl. Total surface area of a cone = \pi r\left ( l+r \right ) l=\sqrt{h^{2}+r^{2}}
What is a curved surface in a graduated cylinder called?
The Meniscus When observing a volume of a liquid in a graduated cylinder, graduated pipette, or buret, read the point on the graduated scale that coincides with the bottom of the curved surface of the liquid. The curved surface of the liquid is called the meniscus.
What are the marks on a graduated cylinder called?
The graduated cylinder will usually have heavy markings at 10, 20, 30, etc. milliliters. There are smaller markings in between the larger units called graduations. Read the graduated cylinder to the nearest tenth of a milliliter (46.5 mL or 20.0 mL).
