How To Calculate Surface Area Gcse Maths Steps Examples 6 × 4 = 24. right side. 24. 2 add the areas together. the sum of the areas is: 40 40 60 60 24 24 = 24840 40 60 60 24 24 = 248. 3 write the answer, including the units. the measurements are in cmcm so the surface area will be measured in cm 2cm2. total surface area = 248cm 2= 248cm2. Example 3: calculate the surface area in terms of pi. a chip shop sells mushy peas in a conical pot. the lid has a radius of 7cm , and the pot has a slant height of 10cm . calculate the outside surface area of the closed pot, including the lid. write your answer in terms of \pi .
Surface Area A Maths Dictionary For Kids Quick Reference By Jenny Eather We then need to find the area of the base of the cylinder: area of a circle = πr2 = π × 72 = 49πarea of a circle = πr2 = π ×72 = 49π. the area of the top of the cylinder is the same as the area of the base so, total surface area: 140π 49π 49π = 238π = 747.699905…140π 49π 49π = 238π = 747.699905…. Surface area of any pyramid = area of base area of each of the lateral faces. if the pyramid is a regular pyramid, we can use the formula for the surface area of a regular pyramid. surface area of regular pyramid = area of base 1 2 ps. where p is the perimeter of the base and s is the slant height. Add together: sum the areas of the circles and the rectangle to find the total surface area. by following these steps, one can systematically compute the surface area, a key skill in gcse maths. troubleshooting common errors. when solving cylinder problems, students often encounter typical pitfalls:. Find the surface area of the cylinder, giving your answer to 4 4 significant figures. [3 marks] we know the formula for the surface area of a cylinder is. surface area = 2\pi r h 2\pi r^2 2πrh 2πr2. from the diagram we can see: – the radius, r, = 12\div 2 = 6 12 ÷ 2 = 6 mm. – the height of the cylinder is 25 25 mm.
