Answer:
7.07cm
Step-by-step explanation:
A=πr2
= 100 π
= 314.159265359/2 (squared)
50% = 157.07963268cm ^2
We look for radius in the area formula
A=πr2
(A / π ) = 157.07963268/ 3.14159265359 = √50 = 7.07106781187
We do not need to half this as already has been squared.

Answer:
1) 194
2) 480
3) 144
4) 2m > 84 $
4m > 168 $
10m> 420 $
13m> 546$
Step-by-step explanation:
1) 582 in 30 mins ... so in third the time 582÷3 = 194
2)120 tools in 5 hours , so 120 ÷ 5 = 24 tools per hour > so 24 × 20 = 480
3) 1kg is for 18$ ... so 8kg will be 8 × 18 = 144
4) 5meters cost 210$ , one meter costs 210÷5 =42
now multiply , 2×42 = 84 , 4×42 = 168 , 10×42= 420 , 13×42 = 546
sorry the last question isn't showing for me , i can't see it
