Question

18. The surface area of a cone is 12611 square meters. The diameter of the 5 points cone's circular base is 22 meters. What is the lateral area of the cone? Round your answer to the hundredths place value. * A 1 5 7 1 +/- B 5 -- C С 3 2 6 7 3 +/- D 1 4 7 0 2 7 +/-

Answer 1

data

Area = 126pi m^2

diameter = 22

TA = pi r h + pir^2

126pi = LA + pi(11)^2

LA = 126pi - 121pi

LA = 5pi
