Answer:
Step-by-step explanation:
AREA of a circle = pi r^2 r = d/2
Area = pi (75/2)^2 = ~ 4418 cm^2
Answer:
4418 cm²
Step-by-step explanation:
You want the area of a 75 cm circle.
The area is given by the formula ...
[tex]A=\dfrac{\pi}{4}d^{\,2}[/tex]
For the given diameter, the area is ...
[tex]A=\dfrac{\pi}{4}(75\text{ cm})^{2}=1406.25\pi\approx4417.86[/tex]
The area of the window glass is about 4418 square centimeters.
