Answer:
The length of the arc is 221π/18 ft or 38.55 ft
Step-by-step explanation:
Given
Subtended angle, θ = 17π/18
Radius, r = 13 ft
Required
Length of the arc.
When an angle is given in radians, the length of the arc is calculated using the formula below
Length = rθ
By substituting
Length = 13 * 17π/18
Length = 221π/18
The answer can be left in this form.
But for simplification purpose, I'll solve further.
Taking π as 3.14
Length = 221 * 3.14/18
Length = 693.94/18
Length = 38.552222
Length = 38.55 ft (Approximated).
Hence, the length of the arc is 221π/18 ft or 38.55 ft
Answer:
Step-by-step explanation:
<h3>Given</h3>
- P = 194
- l = 5w + 25
- l = ?, w = ?
<h3>Solution</h3>
<u>Perimeter formula</u>
<u>Substitute and solve for w:</u>
- 194 = 2(5w +25 + w)
- 194 = 12w + 50
- 12w = 144
- w = 144/12
- w = 12
