Question

a circle has a diameter of 68 cm. what is the area of the circle?

Explanation:

Step1: Calculate the radius

$r = \frac{68}{2} = 34$ cm

Step2: Apply circle area formula

$A = \pi r^2 = \pi \times 34^2$

Step3: Compute the squared radius

$34^2 = 1156$

Step4: Final area calculation

$A = 1156\pi$ cm², or $1156 \times 3.14 = 3629.84$ cm²

Answer:

$1156\pi$ cm² (or approximately 3629.84 cm²)
