Answer:
25.13cm
Step-by-step explanation:
formula for circumference of a circle is (2r)π with r being the radius
since the problem gave us the diameter already we can change the formula to 8π (2r is equal to the diameter since diameter is twice as long as the radius)
this gives us the circumference of 25.13
F(x)=60+0,75x
Because she charges 60 per session, which will not change. And you don’t know how many miles she has to drive so that will be 0,75x.

Answer: y = 5x + 7</h3>
Work Shown:
y - y1 = m(x - x1)
y - (-3) = 5(x - (-2))
y + 3 = 5(x + 2)
y + 3 = 5x + 10
y = 5x + 10 - 3
y = 5x + 7
The equation is now in slope intercept form y = mx+b with m = 5 as the slope and b = 7 as the y intercept. Plugging x = -2 into this equation will lead to y = -3.
Side note: parallel lines have equal slopes but different y intercepts.
Answer:
3) 35.98
4) 63.98
Step-by-step explanation:
3) [(7+7)×3.14÷2]+14=35.98
4) (7+7)×3.14+14×3=63.98
