The area of the base is
.. A = πr^2
The lateral area is
.. A = πrh . . . . . where h is the slant height
The total area is
.. π(r^2 +rh) = πr(r +h)
total surface area = 3.14*(5 m)*(5 m +11 m) = 251.2 m²

Answer:
(- 4, - 10 )
Step-by-step explanation:
y = 5x + 10 → (1)
y = 4x + 6 → (2)
Substitute y = 5x + 10 into (2)
5x + 10 = 4x + 6 ( subtract 4x from both sides )
x + 10 = 6 ( subtract 10 from both sides )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 5(- 5) + 10 = - 20 + 10 = - 10
solution is (- 4, - 10 )
