Question

the csaa of a cone is 670 cm^2 and radius is 15 cm ,then the tsa is

Answer 1

here is your answer tsa= 670×15=10050 cm^2

Answer 2

Total surface area = Curved Surface Area +Area of Base

TSA= πrl +πr^2

TSA= 670 +(22/7 ×15×15)

=670+ 707.14

=1377.14

SO TOTAL SURFACE AREA IS 1377.14 Sq cm
