The way I see it, 325 students went to the trip and 5 had to go in cars so 325 - 5 = 320 then you devide it by 7 because that's the total number of buses which you should get 320/7 Which would equal to 45 students on each bus..
325 - 5 = 320/7 = 45
Hope this helps!
(Btw I rounded to 45 because the whole number was like 45.71428571428571)
Total surface area of a cone is given by,
Surface area of the cone = πrl + B
Here, l = Slant height of the cone
r = radius of the circular base
B = Area of the base
From the picture attached,
Slant height 'l' = 15 in.
Radius of the circular base 'r' = 12 in.
Area of the circular base = πr²
= π(12)²
= 144π in²
By substituting these values in the expression of the surface are,
Total surface area of the cone = π(12)(15) + 144π
= 180π + 144π
= 324π in²
