Assume that the pillars are cylindrical..you're looking for the lateral surface area correct? to get the lateral surface area, you use the formula LSA = 2rh(pi) where r is radius h is height substitute the values... h = 10 d = 1 so r =1/2 so LSA = 2 (1/2)(10)(3.14) LSA = 10(3.14) LSA = 31.4 sq ft :D                                      Can You Mark Me Brainlest Plz...

Answer: He will be painting 125.6 square feet before he buys the paint.

Step-by-step explanation:

Since we have given that

Diameter of pillar = 1 foot

Radius of pillar = 0.5 feet

Height of pillar = 10 feet

Since there are 4 pillars.

We need to paint the 4 pillars.

So, for this we want surface area of each pillar.

As we know the "Lateral surface area of cylinder":

Area=2\pi rh\\\\Area=2\times 3.14\times 0.5\times 10\\\\Area=31.4\ sq.feet

Area of 4 pillars would be

4\times 31.4\\\\=125.6\ sq.feet

Hence, He will be painting 125.6 square feet before he buys the paint.
