 ## Math Tip of the Day: Circle Sector Area

Last week, we discussed one concept of circles:  arc length.  This week’s math tip will be on sector area of circles.  A sector is a section of a circle.  Like a piece of pie or a slice of pizza!  And the sector area is the area of that particular section.   To calculate the sector area, you can set Continue reading ## Math Tip of the Day: Surface Area Part 2

Last week’s math tip was on surface area.  We looked at the two different types of surface area:  lateral and total.  We also provided tips on calculating surface area correctly.  Remember that the formula for total surface area also includes the formula for the lateral surface area.  This makes it easier to calculate.  Last week’s Continue reading ## Math Tip of the Day: Surface Area Part 1

In geometry, there is area.  And there is also surface area.  Surface area is used to find the sum of all the areas of all the shapes of an object.  These objects are usually three-dimensional. It is very easy to calculate surface area.  The hardest part is probably selecting the correct formula to use.  There Continue reading
