7-40.
Find the missing measure(s) of each circle. Homework Help ✎
a. diameter = ? | b. diameter = ? |
Remember:
Circumference = 2 · π · r
Diameter = 2 · r
Use these given formulas to solve for the missing information by substituting in given measurements and solving.
Circumference = 24π = 78.4 cm
Radius = 30 cm
