Question

a math 7 student had a poster with an escher print on it. the diameter of the circle on the poster is 58 cm what is the area of the circle in the poster?

Explanation:

Step1: Calculate radius from diameter

The radius $r$ is half the diameter.
$r = \frac{58}{2} = 29$ cm

Step2: Apply circle area formula

Use the area formula $A = \pi r^2$.
$A = \pi \times 29^2 = \pi \times 841 = 841\pi$ cm²
(Using $\pi \approx 3.1416$, $A \approx 841 \times 3.1416 \approx 2642.0856$ cm²)

Answer:

$841\pi$ cm² (or approximately 2642.09 cm²)
