Answer:
Step-by-step explanation:
for IV you do 40^2+30^2=c, or 1600+ 900=c. c= 2500 and unsquare that you get 50
Answer:
Area of Square= 12*12= 144
Area of Circle= πr2
Radius= 12/2= 6
Area of Circle= 3.14*6*6 =113.04
Area of shaded region= 144- 113.04 = 30.96 = 31.0 (1 dp)

Step-by-step explanation:
it should help :)
The formula is
Sn = a1. 1 - r^n
--------- where r = common ratio and a1 = first term
1 - r
Here we have r = -6 and a1 = -1, and n = 6. So:-
Sum of 6 terms S6 = -1 * 1 - (-6)^6
------------- = 6665
1 - (-6)
