area = pi times radius squared
area = pi times 5 squared
area = pi times 25
area = 78.54
answer : 78.54 square feet
6.7*6.7 to find the surface area of the base which is 44.89
4*1/2*10.1*6.7 to fix the surface area of all four triangular faces which is 135.34
Plus them together 44.89+135.34 which is 180.23
Multiply everything by -3 so it will be n-15>4 then add 15 to both sides so it will be n>19 and thats the answer.
Start by setting the denominator to zero to find the number you will divide by then set it up
