Which of the following belongs to the set of Whole numbers?
0
-5
1╱3

0 is the only option that belongs to the set of Whole numbers.

Step-by-step explanation:

We know that whole numbers:

In general, the set of whole numbers is:

W = {0, 1, 2, 3, ...}

Thus, the set of whole numbers DOES NOT include negative integers and fractions.

Therefore, 0 is the only option that belongs to the set of Whole numbers.

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
