Answer: 490.87
Explanation:
the radius is half of the diameter so radius = 12.5
do the following equation to find the area or a circle: A=πr2
plus in your numbers: A= π·12.52 and solve:
π·12.52≈490.87385
Answer:
≈ 490.87 cm²
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 25, then r = 25 ÷ 2 = 12.5
A = π × 12.5² = 156.25π ≈ 490.87 cm² ( to 2 dec. places )
