Answer:

Option d) 76.44 units^2

Step-by-step explanation:

The approximate area of the circle is equal to the area of one sector, multiplied by 16

The area of one sector is approximate the area of one triangle

A=\frac{1}{2}(b)(h)

we have

b=1.95\ units

h=4.9\ units

substitute

A=\frac{1}{2}(1.95)(4.9)=4.7775\ units^{2}

Multiplied the area of one sector by 16

4.7775*16=76.44\ units^{2}
