Step-by-step explanation:
Multiply 10 by 10, then find the area of the circle (78.54) then subtract, 100-78.54= 21.46. Then round. So its A. 21.5 meters squared
Answer:
A
the area of square is 10²=100
Area of a circle is πr²=π(10/2)²=25π
100-25π=100-25*3.14=100-78.5=21.5
B
it is a simple exchange for goods and services because, is stores value for later use.
4.3*4=17.2
10^2*10^-3=0.1
0.1*17.2=<u> 1.72</u>
