Area of circle is πr^2
Diameter is given =20 cm
Radius r=d/2=20/2=10cm
A=3.14×100
A=314 cm^2
For AC:
AC= root((a-0)^2 + (b-0)^2)
AC= root((a)^2 + (b)^2)
For BD:
AC= root((a-0)^2 + (0-b)^2)
AC= root((a)^2 + (-b)^2)
AC= root((a)^2 + (b)^2)
Therefore,
AC=BD
The equation is -10+(-15). So you take -15 out of the parentheses and you get -10-15 because if you add a negative number then it's just subtracting. So -10-15 is -25. Because 15 less than -10 is -25.
