Answer:
<h2>2,268 square units</h2>
Step-by-step explanation:
Step 1
Find the area of 1 Triangle
To find this, we will use this formula:
Let's use the formula!
<em>The area of 1 triangle is 189 square units</em>
<em></em>
Step 2
Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.
There are 12 sides, so let's multiply 189 by 12
189x12=2268
<h2>
Hence, the area of the regular polygon is 2,268 square units</h2>
Answer: I would go with C I hope i am right!!
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
3x - 13 + 58 = 90
3x - 13 = 90 - 58
3x -13 = 32
3x = 32 + 13
x = 45/3
x = 15
The graph isn’t there u should put a picture of it?
The volume of the original cylinder is
... V = π·r²·h
For r=1 and h=1, this is
... V = π·1²·1 = π
For the new cylinder, the volume is 1.089 times that amount.
... V = 1.089π = π·1.1²·(1-k)
... 1.089/1.21 = 1-k
... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%
The appropriate choice is (B) 10.
