Answer:

A = 0.785m²

B = 31400cm²

C = 7850cm²

D = 785,000mm²

Step-by-step explanation:

To solve this question, we'll have to find the area of a circle which is

Area of a circle = πr²

1. The diameter of the circle = 1m

Area of a circle = πr²

r = radius of the circle

π = 3.14

Radius = diameter / 2

Radius = 1 / 2 = 0.5m

Area = 3.14 × (0.5)²

Area = 3.14 × 0.25

Area = 0.785m²

2. Radius = 100cm

Area of a circle = πr²

Area = 3.14 × (100)²

Area = 3.14 × 10000

Area = 31400cm²

3. Diameter = 100cm

Area = πr²

Radius = diameter / 2

Radius = 100 / 2

Radius = 50cm

Area = πr²

Area = 3.14 × (50)²

Area = 3.14 × 2500

Area = 7850cm²

4. Radius = 500mm

Area = πr²

Area = 3.14 × (500)²

Area = 3.14 × 250,000

Area = 785,000mm²

Answer:

A = 0.785m²

B = 31400cm²

C = 7850cm²

D = 785,000mm²

Use the fomula \pir^{2} to find the area.

If you are having trouble finding the radius divide the diamater by two.

For refrence use 3.14 as pi when multiplying:)

How can you use a table of linear data to predict a value
Anarel [89]
If you have a set of points ( or numbers starting off, like (1,1) and (2,2) or what so ever. you have a slope. As long as you numbers continue to grow, remain constant, or decrease, you have Linear Data

Linear is a smart word for "Straight.

Think of it like this. Your parents give a dollar a day.
Day one you have one dollar
day two you have two dollars.
So if you can figure the slope of the line. you can figure how much you will have in a month!.
