A golf ball has a diameter equal to 4.1cm. Its surface has 150 dimples each of radius 2mm. Calculate the total surface area which is exposed to the surroundings assuming that the dimples are hemispherical.
(Ans: 71.68)
Ans: SA of ball = 4π × ( 4.1/2 )2 = 16.8 π cm2
TSA exposed to surroundings
= SA of ball - 150 × π r2 + 150 × 2π r2
= 16.8 π + 150 π r2
= 71. 68 cm2

How would you solve the equation: 1+ sin(theta)= 2 cos^2(theta)?
Recently I had an insight regarding the difference between squares of sequential whole numbers and the sum of those two whole numbers. I quickly realized the following: x + (x+1)
divide 50 into two parts such that if 6 is subtracted from one part and 12 is added to the second part,we get the same number?
