Answer in cm if you need something else state it in the question.
r = 3 cm h = 7 cm s = 7.61577 cm V = 65.9734 cm³ L = 71.777 cm² B = 28.2743 cm² A = 100.051 cm²
Agenda:
r = radius h = height s = slant height V = volume L = lateral surface area B = base surface area A = total surface area π = pi = 3.14159 √ = square root
