Answer:
lateral area is 329.7 and the surface area is 483.56
Step-by-step explanation:
Lateral area = [tex]\pi (7)(15) = 105\pi = 329.7\\[/tex]
Surface area = lateral area + base area
Base area= [tex]\pi r^{2}[/tex] = [tex]\pi (7)^{2}[/tex] = [tex]49\pi[/tex]
Surface area = 105[tex]\pi + 49\pi = 154\pi = 483.56[/tex]
