If he need 380 to buy the bike but already has35, the he needs 380-35 = 345 more. if he makes 15 a week delivering papers, divide 345 by 15 to get the number of weeks it will take to save. 345/15=23 23 weeks

Step-by-step explanation:
Answer:
length of arc ≈ 17.8 (to the nearest tenth)
Step-by-step explanation:
To find the length of the arc we use the formula for finding length of an arc.
length of arc = ∅/360 × 2πr
where
∅ = central angle
r = radius
∅ = 340°
r = 3
length of arc = ∅/360 × 2πr
length of arc = 340/360 × 2 × π × 3
length of arc = 340/360 × 6π
length of arc = 2040π/360
length of arc = 204π/36
length of arc = (204 × 3.14)/36
length of arc = 640.56/36
length of arc = 17.7933333
length of arc ≈ 17.8 (to the nearest tenth)
The area of the circle is A = π*r²
Given r = 3.2 and π is approximately 3.14, thus
A = 3.14*(3.2)²
A = 32.1536 or 32.15 (rounded off to hundredths place)
