First you need to solve for angle F then you can use 1/2acSinB. If you haven't done this you can also use the Pythagoras theorem and solve for the unknown side once you do that you can just use 1/2 b*h

Find the distance between the points (-4, -5 and (3, -1.
Komok [63]
<u><em>≡ We know that:</em></u>
⇔ (x_{1},y_{1}) → (-4,-5)
⇔ (x_{2},y_{2}) → (3,-1)

<u><em>≡ Solution:</em></u>
⇒ \sqrt{[(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}]}
⇒ \sqrt{[(3-(-4))^{2}+(-1-(-5))^{2}]}
⇒ \sqrt{[7^{2}+4^{2}]}
⇒ \sqrt{[49+16]}
⇒ \boxed{\sqrt{65}}

Find the circumference of this circle. Round to the nearest tenth.<br><br> Area= 63.6 inches squared
Virty [35]

Answer:

C = 28.048

Step-by-step explanation:

Circumference = 2pi(r)

Area = pi(r)^2

62.6 = pi(r)^2

r^2 = 62.6/pi

r^2 = 19.926

r = 4.464

Therefore, circumference = 2pi(4.464)

= 28.048
