SA = 2bA (base area) + LA (lateral area)
bA = r^2*pi = 13^2pi = 169pi cm^2
LA = 2r*pi*h = 2*13*pi*88,4 = 2298,4pi cm^2
SA = (2*169pi)+2298,4 pi = 338pi+2298,4pi = 2636,4pi
Answer:
The number is 20.
Step-by-step explanation:
To solve this, first take the words and turn into an equation.
3/5x + 8 = x
Now we can solve for x using the order of operations
3/5x + 8 = x
8 = 2/5x
20 = x
The angles need to be congruent for the two triangles to be similar.
Hope this helps :)
1/2r+2(3/4r-1)=1/4r+6
2r-2=1/4r+6
2r=1/4r+8
7/4r=8
7r=32
r=32/7
Answer:
there is no way of solving this because the expression does not equal anything.
