Area And Volume vs e++ 3

Calculate a shape’s area or volume from the dimensions you already have. Area And Volume pairs labeled diagrams with formulas, so you can check what each value means as you calculate. CHOOSE THE INPUTS YOU KNOW Find a triangle’s area from its base and height, three sides, or two sides and the included angle. For circles, choose radius or diameter. Ellipses support semi-axis or full-axis lengths; sectors support a central angle or arc length. 16 AREA CALCULATION METHODS Rectangle, square, parallelogram, trapezoid, rhombus, right triangle, general triangle, circle, ellipse, and sector. 6 VOLUME CALCULATION METHODS Cylinder, cone, sliced cylinder, sphere, triangular prism, and triangular pyramid. For the triangular prism and pyramid, enter the known base area and height. CHECK, ADJUST, COPY • See the formula and an explanation of its symbols. • Get updated results as you change the inputs. • Copy the displayed number to another app. • Reset the fields for a new calculation. • Calculate, view formulas, and copy results offline. Useful for geometry practice, checking your work, and everyday dimension calculations. Works on iPhone and iPad, supports English and Simplified and Traditional Chinese, and follows your system’s light or dark appearance. Pro removes ads. Use consistent units for your inputs. Results are rounded to two decimal places. This app does not convert units, measure with the camera, or provide step-by-step solutions.

Students can build prisms/cylinders and pyramids/cones with different bases, and verify the validity of 'Euler's formula' by observing the numbers of vertices, edges and faces of each 3-D figure. Students can also form regular polyhedra and find out their respective 'dual polyhedra'.
