Question

Pythagoras

Answer 1

Answer:

1. $Area = 28.26$

2 and 3: See explanation

Step-by-step explanation:

Solving (1)

$r = 3$ --- radius

The area is:

$Area = \pi r^2$

$Area = 3.14* 3^2$

$Area = 28.26$

There are no enough information to solve (2) and (3) as the radius and/or diameter are not provided.

However, the following formula will be used to calculate the required areas.

$Area = \pi r^2$ --- same process as (1)
