Hello There!
The temperature at 10 am in the morning was 1 degree below zero.
First, we know at 8 am that the temperature was 3 degrees below zero so that number is -3 and it’s our starting number.
Next, it says an hour later the temperature has gone up 6 degrees so we have -3 + 6 and we get a sum of positive 3.
Finally, at 9 am the temperature dropped again but this time 4 degrees so 3 - 4 = -1
The temperature at 10 am in the morning was 1 degree below zero.
Try this solution:
for the circle A: circumference=6π, area=9π
for the circle B: circumference=12π, area=36π
PS. formula for circumference is 'L=2πr', for area is 'S=πr²'.
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.
