Activity 1

Solve for the circumference given its diameter or radius. Use 3.14 for π.

Step-by-step explanation:

• Dia = 18 ft
• r = 9 ft
• C = 2 π r
• = 2 π (9)
• = 18 ft

• r = 11 inch
• d = 22 inch
• C = 2 π r
• = 2×11×π
• = 22 π inch

• D = 35 cm
• r = 35/2 = 17. 5 cm
• C = 2 π r
• C = 35 r cm

Fill in the table

• 1.) r = 4m
• d = 8m
• c = 25.12m

• 2.) r = 6cm
• d = 12cm
• c = 37.68cm

• 3.) r = 15dm
• d = 30dm
• c = 94.20dm
