Step 1: Base Calculations

Question

You will need to decide on the units for your measurements. This will depend on your measuring tool. Once
you have decided what measuring tool and units you will be using, begin by studying the base of your objects.
Measure the base of each item. If the base is a polygon, you will need to measure the length and width. If the
base is circular, you will need to measure the diameter or radius. Record your measurements and include the
units. Using these measurements, calculate the base area of your items. Record these area calculations,
along with proper units. Use 3.14 for π and round your calculations to the nearest tenth of a unit.

Answer 1

Certainly! Let's go through the process step by step.

Step 1: Choosing Measuring Tool and Units

Let's assume you're using a ruler and the units are in centimeters (cm).

Step 2: Measure the Base of Each Item

1. Item 1: Rectangular Base

   • Length: 10 cm
   • Width: 5 cm

2. Item 2: Circular Base

   • Radius: 3 cm

3. Item 3: Square Base

   • Side: 4 cm

Step 3: Calculate the Base Area

Now, we will calculate the base area for each item based on the measurements.

1. Item 1: Rectangular Base

   • Area = Length × Width
   • Area = 10 cm × 5 cm = 50 cm²

2. Item 2: Circular Base

   • Area = π × Radius²
   • Area = 3.14 × (3 cm)²
   • Area = 3.14 × 9 cm² = 28.26 cm²
   • Rounded to the nearest tenth: 28.3 cm²

3. Item 3: Square Base

   • Area = Side × Side
   • Area = 4 cm × 4 cm = 16 cm²

Summary of Measurements and Area Calculations

| Item | Type | Measurement | Area Calculation | Area | |--------|------------|---------------------|-------------------------|--------------| | Item 1 | Rectangle | Length: 10 cm, Width: 5 cm | 10 cm × 5 cm | 50 cm² | | Item 2 | Circle | Radius: 3 cm | 3.14 × (3 cm)² | 28.3 cm² | | Item 3 | Square | Side: 4 cm | 4 cm × 4 cm | 16 cm² |

Now you have measured the bases of the items, calculated their respective areas, and recorded the results with proper units.
