One side is 16cm, divide by two to get 8cm which is the d<span>iameter of one circle.
Divide 8 by two again to get radius and use </span>
= 50.3
Times 50.3 by four to get area of circles, = 201.2.
Do 16 * 16 (area of square) = 256,
256 - 201.2 = (area of white) 54.8
The area of the white is 54.8.
Hope this helps.
Alright
so
28% of 2 m³=0.28 times 2=0.56 m³ of silt in the first mixture
13% of the 1 m³=0.13 times 1=0.13 m³ of silt in 2nd
total is 0.56 m³+0.13 m³=0.69 m³ of silt
and the total is 2m³+1m³=3m³
so
0.69/3=0.23=23%
answer is D
