awnser: 42
step by step:
1. find the racio of both
2.multiply the awnsers by 7
3.finally subtract
Answer:20.096
Step-by-step explanation:
radius =r=4
Φ=288
π=3 14
Length of arc=Φ/360 x 2 x π x r
Length of arc=288/360 x 2 x 3.14 x 4
Length of arc=0.8 x 2 x 3.14 x 4
Length of arc=20.096
The wire is about 11.18 m long. This can be found using the Pythagorean theorem.
I think it's 85 but Is this like a multiple choice question?
