Answer :
x = 53.85
Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.
1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42
2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85
3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :
42/0.78 = 53.85
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...
