Answer:
lateral surface area= 109.97 in^2
Step-by-step explanation:
The lateral surface area of a cone is given by the expression
[tex]LSA= \pi rl[/tex]
Given
diameter= 7 inches
radius= 7/2= 3.5 inches
slant height l= 10 inches
substituting the data into the formula we have
[tex]LSA= 3.142*3.5*10= 109.97 in^2[/tex]
