Title: Time coversations

Grade: 6-a Lesson: S2-L8

Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

A circle has radius of 2 meters. What is the surface area of the circle?

Step 1a

The surface area of a circle can be found using the formula:

\$ A = π * r^2 \$

where A represents the surface area and r is the circle’s radius.

Explanation: Here, we know the formula for the surface area of a circle.

Step 1b

Given that the radius of the circle is 2 meters, we can substitute this value into the formula:

\$ A = π * (2 "meters")^2 \$

\$A = π * 4 "square meters" \$

\$A ≈ 3.14159 * 4 "square meters"\$

A ≈ 12.56636 square meters

Therefore, the surface area of the circle with a radius of 2 meters is approximately 12.57 square meters

Explanation: Here, we substitute the radius in the surface area of a circle.
