Answer:

The approximate area of the circle is 27.5184∧2

Explanation:

In order to calculate the approximate area of the circle we would have to calculate the following formula:

approximate area of the circle=approximate area of one triangle*number of congruent sectors

number of congruent sectors=16

approximate area of one triangle=1/2*base*height

base=1.17 units

height=2.94 units

Therefore, approximate area of one triangle=1/2*1.17*2.94

approximate area of one triangle=1.7199 units∧2

Therefore, approximate area of the circle=1.7199 units∧2*16

approximate area of the circle=27.5184∧2
