Basically, r=2t
A(r)=pir^2
sub 2t for r
A(2t)=pi(2t)^2
A(2t)=4pit²
A. A=4pit²
B. t=5
A=4pi5²
A=4pi25
A=100pi
A=314 square units

69. The jacket is said to have an original price of 45.00 dollars.
Now, is was given a 25% off.
Solve for the final cost of the jacket after the discount is applied.
=> 25% = 25% / 100% = 0.25
=> 45.00 * .25 = 11.25 dollars is the discount.
Now, let’s subtract the value of 25% by the original value.
=> 45 – 11.25 = 33.75 dollars.
This is now the costs of the jacket after the discount is applied.
