Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = <u>2</u><u>*</u><u>√</u><u>1</u><u>5</u><u> </u>
2
A = √15cm²
Answer:
Don’t quite me on it, but 45cm?
Explanation:
Well, if the shortest rope (4) is only 20cm, it’s about 5cm per length (?)
So, if you follow that pattern the longest (9) would be 45cm.
Just add 2/5+2/5+2/5.
Add: 2 2 2 ----- numerators
---- + ---- + ----- =?
5 5 5 ------- denominators
Add your numerators first: 2+2+2=6
Leave your denominators alone they are all 5 so that's ok.
Your answer will be 6
------
5
Hope I helped:)
Hello!
To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.
C = 2(36)π
C = 72π
Therefore, the circumference of the circle is 72π inches.
