Answer:
12) +2
13) Circumference of circle = 2πr
44m = 2×22/7×r
44m×7/44=r
7m=r
Area of circle = πr²
= 22/7 × 7 × 7
= 22×7
= 154m²
14) 1/4 × 100 = 25%
16) let the 4 consecutive no. be x, x+1, x+2, x+3
So, x+x+1+x+2+x+3=216
=> 4x+6=216
=> 4x = 216-6
=> x = 210/4
=> x = 52
1st con. no. = x = 52
2nd con. no. = x+1 = 53
3rd con. no. = x+2= 54
4th con. no. = x+3 = 55
17) 1/6
Plz.. mark it the brainliest..
