Question

The clock face in a famous clock tower has a radius of about 5 meters. What is the area of the clock face to the nearest square meter? Use 3.14 as an approximation for .

Answer 1

Area =
`\pi` * r^2 = 3.14 *25 = 78.5 m sqaure.
79 square meter when you round it up

Answer 2

The area of the clock face is
`79\ m^(2)`

Explanation:

we know that

The area of a circle is equal to

`A=\pi r^(2)`

we have

`r=5\ m`

`\pi=3.14`

substitute

`A=(3.14)(5^(2))=78.5\ m^(2)`

Round to the nearest square meter

`78.5\ m^(2)=79\ m^(2)`
