WebThe radius of the circle = 14 cm. Area of a circle is calculated by the formula π r 2. Substituting the values in the formula, area = 22 7 22 7 × 14 × 14 = 616 square cm. … WebThe two distinct measures used to define the three-dimensional shapes are volume and surface area. Generally, the three-dimensional shapes are obtained from the rotation of two-dimensional shapes. Thus, the surface area of any 2D shapes should be a 2D shape. If you want to calculate the surface area of solid shapes, we can easily calculate from ...

The area of a trapezoid is calculated by multiplying the average width by the altitude. See Trapezoid definition (coordinate geometry) to see how the side lengths and altitude are found. (Note too that the median length is the same as the average width.) In the figure above, drag any vertex of the trapezoid and note how the area is ... WebHow Does it Work? We start with this formula: Area = ½ × base × height We know the base is c, and can work out the height: the height is b × sin A So we get: Area = ½ × (c) × (b × sin A) Which can be simplified to: Area = 1 2 bc sin A By changing the labels on the triangle we can also get: Area = ½ ab sin C Area = ½ ca sin B One more example: ph-import planter
