- So, \( 2(2w + w) = 36 \).
- Simplify: \( 2(3w) = 36 \) ⟹ \( 6w = 36 \) ⟹ \( w = 6 \).
- A circle has a radius of 7 units. What is the area of the circle, rounded to the nearest whole number? (Use \( \pi \approx 3.14 \))
- So, \( \text{Area} = 3.14 \times 7^2 = 3.14 \times 49 \).
- Calculate: \( 3.14 \times 49 = 153.86 \).
- Rounded to the nearest whole number, the area is 154.
