When it comes to geometry, surface area of prisms and cylinders are important topics for students to understand. For those who have been assigned homework 5 focused on the surface area of prisms and cylinders, this answer key will be of great help.
Surface Area of Prisms
The surface area of a prism is equal to the sum of the areas of its faces. This means that to calculate the surface area of a prism, students need to calculate the area of each face and add them together. The formula for the area of a rectangular prism is l x w x h, where l stands for length, w stands for width, and h stands for height. For triangular prisms, the formula is B x h, where B stands for base and h stands for height.
Surface Area of Cylinders
The surface area of a cylinder is equal to the sum of the area of its curved surface and the area of its two circular ends. To calculate the surface area of a cylinder, students need to calculate the area of the curved surface and the area of each circular end and add them together. The formula for the curved surface is 2πrh, where π stands for pi, r stands for radius, and h stands for height. The formula for the area of each circular end is πr2, where π stands for pi and r stands for radius.
Tips to Calculate Surface Area of Prisms and Cylinders
When calculating the surface area of prisms and cylinders, students should first identify the type of prism or cylinder they are working with. They should also make sure to use the right formula and to double check their work after they finish calculating. Additionally, it is important to note that when calculating the surface area of a cylinder, the radius and height should be measured from the same base point.
Calculating the surface area of prisms and cylinders can be a challenging task for students, but with the right formulas and tips, they can easily complete their homework 5 assignments. With this answer key, students can easily understand the concepts behind surface area of prisms and cylinders and successfully complete their homework.
