Option D
Step-by-step explanation:
If the whole grid is considered to be 1,
Each small grid will value =
There are 72 shaded grids which represent the hundreds = 0.72
When these grids have been divided into 9 equal rows, number of grids in each row = 8
And the value of 8 grids in each row = 0.01 × 8 = 0.08
So the equation is,
0.72 ÷ 9 = 0.08
Therefore, equation represented by the model will be Option (D).
Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is . With r=50,
=2500π which is about (2500)(3.14)=7850.
The perimeter is which is the same as (diameter)(π). The diameter is 100, so
which is about (100)(3.14)=314.
