Work out the area of this circle. Take it to be 3.142 and give your answer to 1 decimal place.

4 cm

→

→Step-by-step explanation:

Well the formula for the area of a circle is .

→Given information

Pi is 3.142

radius is 4 cm

answer must be rounded to the nearest tenth

____________________________________________________________

So now we have to plug in the given information into the following formula .

(3.142)(4)^2

So now we have to solve this formula using PEMDAS.

So 4 squared is 16 and 16*3.142 is 50.272cm^2.

The question clearly states the given answer must be rounded into the nearest tenth so 50.272 is 50.3 cm^2.
