The correct answer is D because you would multiply the numbers in the bracket by 6 which would equal to 30
I believe its between the integers of 7 and 8.
Total surface area of cone: πrl + πr²
Assuming the bottom of the cone is closed.
r = r/2, l = 2l
Total surface Area = π*(r/2)*2l + π(r/2)² = πrl + πr²/4
Total Surface Area = πrl + πr²/4
Distance or meters and speed
