Answer:
496.6
Step-by-step explanation:
circumference of circle=8pie^2
2*pie*r=8*pie^2
2*r=8*pie
2r=8*22/7
r=176/7÷2
r=12.57
Area of circle=pie*r^2
=22/7*12.57^2
=22/7*158
=496.6
2,4 is the correct coordinates
Answer:
It’s just subtraction
Step-by-step explanation:
When a square is in the middle its 90 so just subtract the other number by 90
Step-by-step explanation:
1. 10s2 + 10s2 - 13st = 20s2-13st
2. 13st + - 2st - t2 = 11st - t2
3. x2+ x2 + x3= 2x2 + x3
4. 6 x - 6 x + 2=X+2
5. 24x - 3s - 4t=24x - 3s - 4t
6. 86 + 86x - 1=85+86x
7. 4x + 3x - 2 =7x - 2
8. 7s - 4s + 3s =6s
9. 12 +11x - 10 x = 12+x
10. 12x + 24 x - 3 x - 4 =33x -4
11. 16t + 8t - 12t =12t
12. 17g + 19g - 2g +g =35g
13. 16 + 16 -16 + 16x =16+16x
14. 4s - 3s + 3s =4s
15. 12t - 11t + t =2t
The symbols, you mean? Those are called "parentheses".
