Basically
Circumference = 2 * pie * radius
To get the radius u need to measure the circles distance. For example I measured a circular mirror and the distance was 10cm. This is the diameter. To get the radius I’ll divide by 2 because the radius is from the centre of the circle to the edge. So, 10 divided by 2 = 5cm. The radius is 5cm. Now,
Circumference = 2 * pie * r
r = 5. Pie = 3.14
Circumference = 2 * 3.14 * 5
= The answer
****pie is always 3.14
I hope you understood
Answer:
Terrance would take 4.2666 hours, Jesse would take 6.25 hours
Step-by-step explanation:
1h/12m per hour x 50m/1h is also 50m/12m per hour = 4.266 hours (round number)
1h/8m per hour is also 50m/8m per hour = 6.25 hours (round number)
It is 32.8 I just did %in my class today
Answer:
B
Step-by-step explanation:
because it explains what the graph shows
For the answer to the question above,
<span><J = 100
</span><span>because they are similar they have the same angles
</span>The two triangles are similar, so they must have corresponding angles. Thats one way to define similarity, it can dilate (zoom in /zoom out) , but the angles are preserved. You can also define similarity in terms of the proportionality of the sides.
"Given △ABC≅△JKL"
The order of the letters counts.
<A = <J
<B = <K
<C = <L
<span>now you can draw two generic triangles, which have the same three angles, but label the angles accordingly, so they match up.
</span>
<span>then by correspondance we can fill in
</span>nightowlthe third angle can be found by the fact that
the three angles must add up to 180.
