Answer:
25,133 m^2
Step-by-step explanation:
The lateral area of a cone is found using the slant height (s) and the radius (r) in the formula ...
A = πrs
So, we need to know the radius and the slant height.
The radius is half the diameter, so is (160 m)/2 = 80 m.
The slant height can be found using the Pythagorean theorem:
s^2 = r^2 + (60 m)^2 = (80 m)^2 +(60 m)^2 = (6400 +3600) m^2
s = √(10,000 m^2) = 100 m
Now, we can put these values into the formula to find the lateral area:
A = π(80 m)(100 m) = 8000π m^2 ≈ 25,133 m^2
Answer:
15
Step-by-step explanation:
Given the function
and 
let f(x)=y
Substitute in f(x)
From the definition inverse function
if 
⇒ 
Substitute this in the above expression
Substitute y=10
⇒
Therefore a=15
The answer is 15 cubes with side lengths of 0.5 inches. I did this by adding up all the edge lengths then dividing the answer by 0.5 inches
