Question 6 options: What is the approximate area of a circle with a diameter of 56 cm? Use your calculator button for π. Round y

Andrew [12]

The area of circle is 2463.0086 cm².

Step-by-step explanation:

Given,

Diameter of circle = 56 cm

Radius of circle = $\frac{Diameter}{2}$

Radius of circle = $\frac{56}{2}=28\ cm$

We know that;

Area of circle = $\pi r^2$

Area of circle = $\pi *(28)^2$

Area of circle = π * 784

Area of circle = 2463.00864041 cm²

Rounding off to four decimal places

Area of circle = 2463.0086 cm²

The area of circle is 2463.0086 cm².
