Answer:

area of the circle= πr²

we have the value of r=7.5

area= 3.14×(7.5)²

=3.14×56.25

=176.625cm²

Step-by-step explanation:

here is ur answer if u understand comment in my answer

Final answer:

The area of a circle with a radius of 7.5 cm is calculated using the formula A = πr², yielding an approximate result of 176.7 cm².

Step-by-step explanation:

To calculate the area of a circle, the formula A = πr² is used, where A represents the area and r is the radius of the circle. If the radius is given as 7.5 cm, we can insert this value into the formula and calculate the area as follows:

A = π × (7.5 cm)²

Using 3.1415927 as the value for π (pi) and rounding our answer to one decimal place, we have:

A = 3.1415927 × 56.25 cm² = 176.714586 cm² ≈ 176.7 cm²

Therefore, the area of the circle is approximately 176.7 cm² to one decimal point.
