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

Circle Area & Circumference Problems Solved | Step-by-Step Geometry

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 $r = d/2$

Reading Comprehension: Lila's Special Helper Chart

🌟 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?"
