Answer:
EF = 58 units
Step-by-step explanation:
Given:
DF = 9x - 39
DE = 47
EF = 3x + 10
Find:
EF
Computation:
DF = DE + EF
9x - 39 = 47 + 3x + 10
9x - 3x = 47 + 39 + 10
6x = 96
x = 16
EF = 3x + 10
EF = 3(16) + 10
EF = 58 units
All we have to do here is to calculate the circumference of the metal frame.
The formula for circumference in terms of diameter d is C = p*d.
Thus, the desired answer is C = 3.14(12 ft) = 37.7 feet (rounded up from 37.68 feet).
Answer:
The answer is B.
