First, you need to find 25% of 52.60
Convert 25% to decimal:
25% = .25
Find 25% by multiplying its decimal equivalent by the sales price.
.25 x 52.60 = 13.15
Next, subtract that amount from 52.60 to find the new sale price.
52.60 - 13.15 = 39.45
The final price is $39.45
The perimeter of R is the same as the perimeter of L
Answer:
a) 11%
b) 56%
Step-by-step explanation:
a) A= πr^2 6^2π= 36π A= 18^2π = 324π
36π/324π = .111111111111111111111111 or 11%

b) A= πr^2 18^2 π = 324π
A= πr^2 12^2π = 144π
324 – 144 = 180
180π/324π = .5555555555555555555555556 or 56%
