What is the arc length when θ = 3 pi over 5 and the radius is 7 cm? (5 points)

1 answer:

4 0

The correct answer is 21π/5

Explanation:
The arc length of a circle is given as = radius × angle subtended by the arc at centre.
Here, r = 7 cm.
θ = 3π/5
Therefore, arc length, l = rθ = 7×3π/5 = 21π/5

HELP!!

Lets convert

1mile=5280ft
1h=3600s

$\\ \rm\longmapsto 1mph$

$\\ \rm\longmapsto \dfrac{5280}{3600}ft/s$

$\\ \rm\longmapsto 1.46ft/s$

If rounded

$\\ \rm\longmapsto 1.5ft/s$

What should the balance be in Diane's register?<br><br> Will give BRAINLIEST

MArishka [77]

Answer:

The balance of Dianne's register should be $359.41

Step-by-step explanation:

We can begin at the ending balance on the bank statement at $578.30

Then a check is written for $219.25, so a debit

Next a deposit is made for $140.36, so a credit

Then a withdrawal is made for $140.00, so a debit

This means we can make the equation

$578.30-219.25+140.36-140.00=359.41$

Answer:

25.1!

Step-by-step explanation:

all you have to do is C=2πr=2·π·4≈25.13274

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).

Hope that helped! :)

Find the x and y intercepts 8x-4y= -16

scZoUnD [109]

$8x-4y=-16\\\\x-intercept\ for\ y=0:\\\\8x-4(0)=-16\\\\8x-0=-16\\\\8x=-16\qquad\text{divide both sides by 8}\\\\\boxed{x=-2\to(-2,\ 0)}\\\\y-intercept\ for\ x=0:\\\\8(0)-4y=-16\\\\0-4y=-16\\\\-4y=-16\qquad\text{divide both sides by (-4)}\\\\\boxed{y=4\to(0,\ 4)}$
