## LeahAnnEvans19 Group Title What is the area of a circle with a radius of 4 meters? Use 22/7 for pie . 2 years ago 2 years ago

1. FoolForMath

Area of a circle is given by $$\pi r^2$$, where $$r$$ is the radius. So, $$\frac {22}7 \times 4^2 = \frac{352}{7}$$ sq mt

2. FoolForMath

$$= 50.2857$$ sq mt

@FoolForMath, do you guys use the abbreviation $$\text{mt}$$ rather than $$\text{m}?$$ In the states, it's always $$\text{m}.$$ Just curious.

No we use 'm' typically but I have seen the usage of 'mt' :)
