Answer: 520.5 m²
This answer is not an answer choice provided, but I hope this still helps.
Step-by-step explanation:
The formula to find the surface area of a cone is 
. Looking at the formula, we can see there are radius and height. The figure provided gives the radius is 7.1 m and height of 14.6 m. Since we have these values, we can just plug them into the formula.
Now that we have filled out the formula, we can plug this into a calculator to get the surface area. It is possible to do this by hand, but it is hard to be accurate.
Hello from MrBillDoesMath!
Answer:
48x + 72y
Discussion:
8(3(2x+3y)) = => as 8*3 = 24
24 (2x + 3y) =
24*2x + 24*3y =
48x + 72y
Thank you,
MrB
A shape is similar if corresponding angles are equal & if one is an enlargement of the other.
(I. E., one shape is twice as big as the other one.)
So, compare the lengths to find a common scale factor (of 2, for example, where you multiple by 2 to get a value & divide to get original value, from one shape to another.)
Hope this helps!
