Answer:
............................
12+4+9+13+7+11+5+2+_+_ /10= 8
x10 both sides
12+4+9+13+7+11+5+2+_+_=80
63+_+_=80
-63 both sides
_+_= 17
any two numbers that add up to 17 can go in the planks
7,10
Step-by-step explanation:
1.The formula in finding the area of a circle is derived from the area of a parallelogram. It is false.
2. The area of a circle is πr² where r is the radius of the circle. It is true.
3. The area of a circle is equal to pi divided by the square of the radius. It is false.
4. The diameter of a circle is equal to twice its radius i.e. d = 2r. It is true.
5. If r = 2.1 m
Area of circle, A = πr²
= 3.14 (2.1)²
= 13.85 m²
Henc,e this is the required solution.
