Total surface area is the total area, in square meters, of the outside surface of an object. In the case of a geometric shape like a cube or cylinder, it is the sum of the area of the individual faces or surfaces of the shape.What...
Total Surface Area=2πr(h+r) where:- r is the radius of the base of the cylinder,- h is the height of the cylinder,- π is a constant approximately equal to 227 or 3.14. Given:- Radius r=7 cm- Height h=15 cm Step 1: Substitute the values into the formula Substituting the val...
To solve the problem step by step, we will use the formulas for the total surface area and the curved surface area of a cylinder. Step 1: Understand the given informationWe know:- Total Surface Area (TSA) = 462 cm²- Curved Surface Area (CSA) = (1/3) * TSA Step 2: Write the...
Obtaining the area of a simple two-dimensional shape like a circle or rectangle requires following a simple formula, but determining the total surface area of a three-dimensional object like a cone or closed cylinder requires the use of multiple formulas. A cylinder's surface area is composed o...
