Answer:
C) 26π mi
Step-by-step explanation:
1. Find the diameter:
<em>24² + 10² = d²</em>, because of the pythagorean theorem.
Add: 676 = d²
Square root: <em>26 = d</em>, no negatives by domain
2. Find the circumference:
<em>C = dπ</em>
Plug in: C = 26π miles
Answer:
15
15
Step-by-step explanation:
x + 20 = 35
- 20 -20
x = 15
5x - 14 = 16 + 3x
+ 14 +14
5x = 30 + 3x
-3x - 3x
2x = 30
x = 15
The answer is 387.71
Formula: pi * r (r + (square root of h^2 + r^2) )
Plug in and solve.
Answer:
36 units
Step-by-step explanation:
to do this you must first find the lengths of all the sides with pythagorean theorem
for a to b you use
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
c = 5
5 is one of the lengths
b to c uses the same equation
so
5 is another one of the lengths
for d to c your equation is
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
13 is another of the lengths
d to a has the same length as c to d so there is another 13 unit length
so
5 + 5 + 13 + 13 is your equation to find the perimeter
5 + 5 + 13 + 13 = 36
that is your answer
