In the equation for surface area the radius is squared ( r^2) 
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.

Answer:
tatol price= $335.16
Step-by-step explanation:
regular price for one item= $168
sale=1/2 % 
168 × 0.5/100 = 0.84 (discount)
price of discounted chair= 168-0.86
                                          = 167.16
168+167.16 = $335.16
