Step-by-step explanation:
Did you mean :
f(x) = 5(4 - x)
f(16) = 5(4 - 16)
f(16) = 5(-12)
f(16) = -60
Answer:
B. 2.2π m² : 3.2π m²
Step-by-step explanation:
Given:
Slant height (l) = 2.2 m
Diameter (d) = 2 m
Radius (r) = ½(2) = 1 m
Required:
Lateral area and surface area
Solution:
✔️Formula for lateral area of a cone = πrl
Plug in the values
Lateral area of the cone = π*1*2.2
Lateral area = 2.2π m²
✔️ Formula for surface area of a cone = πr(l + r)
Plug in the values
Surface area of the cone = π*1(2.2 + 1)
Surface area = π(3.2)
Surface area = 3.2π m²
The answer would therefore be:
2.2π m² : 3.2π m²
Answer:
(-5/2 , 2)
Step-by-step explanation:
add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.
