Perimeter = (πr + 2r), where "r" is the radius of the semicircle and π is a constant with a value of 22/7. In terms of diameter, the formula is expressed as, Perimeter = π(d/2) + d, where 'd' is the diameter of the semicircle. ...
To find the perimeter of composite shapes we will add the lengths of the sides. For finding the value of unknown x first, we know that the radius of thesemicircleis 20 cm, the distance between the 60 cm and 90 cm sides is 40 cm. The hypotenuse of the right triangle can be found by...

A circle has a one size fits all formula to find the area: Acircle=πradius2 The key to using this formula well is understanding the other measurements of a circle, and how to apply this area formula to sectors and pieces of a circle. The angles of a circle are often measured in deg...
Volume of a Cone A cone is a shape with a circular cross-section that tapers to a point. If the radius of the cone at its widest point is r and the length of the cone h, you can find the volume using calculus, or you can do as most people do and look it up....
Step 1: Draw the profile curves with the sketch. Then use them to create thesurface. Firstly, create the sketch1 on XY plane. It is an ellipse with size of 280mm*210mm. Then, create the sketch2 on YZ plane. It is a semicircle with radius 40mm, and the center of the circle is ...
