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
Do you know how to graph by finding the x and y intercepts? Or can you solve for y so your equation looks like y=mx+b?
Answer:
huh
Step-by-step explanation:
did you add anything?
Answer:
A and C and E
Step-by-step explanation:
Circumference is = 2*pi*r
Answer:
6x^3 - 4x^2
Step-by-step explanation:
f(x) = 2x^2 and g(x) = 3x – 2
(f*g) (x) = 2x^2 * (3x-2)
= 6x^3 - 4x^2
