Detail: Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
26 Common Core State Standards (CCSS) aligned worksheets found:
Students will need to find both the area and circumference for each circular shape.
Either the diameter or the radius is shown on each shape. Calculate the area for each.
Use the formula pi-r-squared to calculate the area of each circle.
The diameter of each circle is shown.  Students must calculate the circumference, or the distance around the circle.
Determine the area of each circle. Includes a sample problem at the top.
In this activity, students use a tape measure  to determine the circumference and diameter of circles.  Then they use their data to calculate pi.
Each circle picture shows a radius or diameter.  Students must use this information to figure out the circumference.
A radius is drawn on each circle shape.  Find the area of the circle.
The radius of each circle is drawn. Pupils must figure out the distance around the edge of the circle, or circumference.
This is a series of short-answer questions that relate to pi, circles, and circumference.
Practice calculating S.A. using the mathematical formula SA = 2(h x w) + 2(w x l) + 2(l x h).
Determine the diameter, radius, and circumference of each of these circles.
Calculate the surface area of three solid shapes. This worksheet includes space for students to show their work.
Using the given formula, figure out the SA of three triangular prisms.
This worksheet has three solid shapes, with the dimensions labeled. Students determine the SA of each. Includes plenty of space to show work.
Find the diameter and radius of  each circle.  Also, figure out which circles are the largest, which are the smallest, and which are the same size.
This printable activity has four graphical shapes. Pupils calculate the surface area for each. Then they solve two word problems.
Given the radius or diameter, calculate the areas of the circles.
This worksheet has an explanatory box to show students how to solve surface area problems. Then there are asked to find the SA for three different rectangular prisms.
Use the given formula to determine the surface area of the spheres. Includes a sample, plus three spheres to solve.
