Question

a disk is shaped like a flat circular plate. its radius is 4.25 inches. to the nearest hundredth, what is the area of the disk? use 3.14 for π. enter the correct answer in the box. show hints

Explanation:

Step1: Recall area of circle formula

The area $A$ of a circle is $A = \pi r^2$

Step2: Substitute given values

Substitute $r = 4.25$, $\pi = 3.14$:
$A = 3.14 \times (4.25)^2$
First calculate $(4.25)^2 = 18.0625$

Step3: Compute the product

$A = 3.14 \times 18.0625 = 56.71625$

Step4: Round to nearest hundredth

Round $56.71625$ to two decimal places: $56.72$

Answer:

56.72 square inches
