Answer:
7,539.14
Step-by-step 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
Step-by-step 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
