Answer:
a 34
b 134
c 140
Step-by-step explanation:
a) 180 - 146 = 34
b) 180 - 46 = 134
c) 180 - 40 = 140
To find the total surface area of this cone, we have that the total lateral area is given by the formula:
Where
s is the slant height of the cone, s = 12 inches.
r is the radius of the base of the cone, r = 7 inches.
To that area, we need to add the area of the base of the cone:
That is, this is the area of a circle with this radius. Then, the total surface area is:
Substituting the values in this formula, we have:
Then
Hence, the total area is equal to 417.62 square inches.
Answer:
m=−2,y=1
Step-by-step explanation:
If you would like to solve the equation q * x + r * x = s for x, you can do this using the following steps:
q * x + r * x = s
x * (q + r) = s /(q + r)
x = s / (q + r)
The correct result would be x = s / (q + r).
