Answer:
A
Step-by-step explanation:
Think of a circle. We know it (and all circles) measure 360°. If you think about bisecting that circle, you would divide its 360° by 2, which results in 180°. The circle becomes a half-circle after being bisected, and its straight side (a straight angle) is 180°.
I've attached a diagram illustrating this.
The answer is 430, since it is asking for 10%, 10 x 10 is 100. Considering that with 43, is 43 x 10. 43 x 10 = 430.
Answer:
400 cm squared
Step-by-step explanation:
Area of Square = length*length.
A=20*20
A=400 cm squared
Answer:
The second one, the second to last one, and the last one.
Step-by-step explanation:
The second one is negative because if you add a negative number with a positive number it becomes negative.
The second to last one is zero because if you add a negative and a positive number that is the same number then it becomes zero.
And the last one, they are both simply positive.
Hope this helps <3
