A Correct answer
Explanation

The formula for calculating the surface area of a rectangular prism is SA = 2 * (l * w + w * h + l * h), where l is the length, w is the width, and h is the height of the prism.

Multiple choice

Find the area of a circle with radius 7 cm.

  1. 154 cm^2

  2. 147 cm^2

  3. 133 cm^2

  4. 122 cm^2
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The area of a circle is calculated using the formula: $$Area = \pi r^2$$ Substituting the given radius, we get: $$Area = \pi \times 7^2$$ $$Area = \pi \times 49$$ $$Area = 154 cm^2$$
