Area and Circumference of Circle- WS2

Circle Problems: Area & Circumference Practice (Part 2)

9) A student is using a hula hoop with a diameter of 80 cm.

1. How many meters does the hula hoop travel in one complete rotation?
   Convert to meters: 80 cm = 0.8 m

   Circumference: $3.14 \times 0.8 = 2.512 \text{ m}$

   Answer: 2.512 meters
2. If the student spins the hula hoop 25 times, what is the total distance the edge of the hoop travels?
   Calculate: $2.512 \times 25 = 62.8 \text{ m}$

   Answer: 62.8 meters

Circle Problems: Area & Circumference Practice (Part 1)

1) The Grade 7 class is having a pizza party! Mr. Jones ordered a giant circular pizza with a diameter of 60 cm.

1. What is the circumference of this delicious pizza? Show your work.
   Formula: $C = \pi d$

   Substitute: $C = 3.14 \times 60 \text{ cm}$

   Calculate: $C = 188.4 \text{ cm}$

   Answer: 188.4 cm
2. If each student needs at least 75 cm² of pizza, how many students can this one giant pizza feed? Show your work.
   Radius: $r = 60/2 = 30 \text{ cm}$

   Area: $3.14 \times 30^2 = 2826 \text{ cm}²$

   Students: $2826 ÷ 75 ≈ 37.68$

   Answer: 37 students

Area and Circumference of Circle- WS1 Solutions

Step-by-Step Solutions: Area and Circumference of Circles

This page provides detailed solutions for various problems involving the calculation of the area and circumference of circles. We will use the following key formulas and the approximation $\pi \approx 3.14$.

• Circumference ($C$) using diameter ($d$): $C = \pi d$
• Circumference ($C$) using radius ($r$): $C = 2 \pi r$
• Area ($A$) using radius ($r$): $A = \pi r^2$
• Relationship: $d = 2r$ or $r = d/2$

🌟 Lila's Special Helper Chart

Lila loved seeing gold stars on her school projects, so she had a bright idea. "Mom, can I make a helper chart for chores?" she asked. Her mom smiled. "Great idea! Let's start small. How about setting the table for dinner?"

Lila drew a chart with seven boxes, one for each day of the week. Every night, after she carefully placed forks, plates, and cups around the table, her mom added a shiny star. By Wednesday, Lila had three stars. But when her little brother spilled juice all over the table, Lila groaned. "Now I have to clean and set the table again!"
