π = 3.14 and d = diameter

To get the increase, we must find the area of the circle when the radius was 2 inches and subtract it from the area of the circle when the radius increases to 3 inches. The difference is the increase in the area of the circle.
A circle of radius r has an area A given as
A = Pi r²
Hence when the radius was 2 inches, the area A
= Pi × 2²
= 4 Pi square inches
when the radius increases to 3 inches, the area
= Pi × 3²
= 9 Pi square Inches
The increase in area
= 9 Pi - 4 Pi
= 5 Pi
I believe its 24in not sure cause i got it on a not really reliable website
153.94 square inches
A = Pi(r)^2
A = Pi(7)^2
A = Pi(49)
A = 153.93804
Step-by-step explanation: All you have to do is multipy the area of the original figure by the scale factor. (18 times 2) which is 36.
You're welcome <3
A yard is 36 inches so a square having 4 sides would be 9 inches
I think it might be 60in.
Hope this helps.
Pythagoras theorem: a² + b² = c²
2*a² = 8²
A = 8²/2
