Answer:

7,539.14

Explanation:

To solve for area, square the radius (radius times radius) then multiply by 3.14.

A=pir^2

The diameter is 98mm

pi= 3.14

r= 49^2=

49 X49= 2,401

2,402 X 3,14= 7,539.14

Answer:

A = 7539.14 mm^2

Explanation:

Area of a circle is given by

A = pi * r^2

We need to know the radius

r = d/2

r = 98/2

r = 49 mm

The radius is 49 mm and pi = 3.14

A = 3.14 * (49)^2

A = 7539.14 mm^2
