Answer:
The area of the circle is A = 12.56 m²
Step-by-step explanation:
* Lets explain how to solve the problem
- The area of any circle is A = π r² , where r is the radius of the circle
- In any circle the length of the radius is half the length of its diameter
* Lets solve the problem
- The diameter of the circle is 4 meters
∵ The radius of the circle = 1/2 diameter
∵ The diameter = 4 meters
∴ The radius = 1/2 × 4 = 2 meters
- The area of the circle is A = π r²
∵ The value of π = 3.14
∵ The length of r = 2 meters
- Substitute the value of r in the rule of the area
∵ A = π r²
∴ A = 3.14 × (2)²
∴ A = 3.14 × 4 = 12.56 meters²
* The area of the circle is A = 12.56 m²
Answer:
a) C(x) = 4x + 350
b) 13x; $13
c) 39
Step-by-step explanation:
a) Initial cost of lawnmower = $350
Maintenance cost for 1 lawn = $4
Maintenance cost for x lawns = 4x
Total cost function, C(x) = 4x + 350
b) Revenue = Cost + Profit
= C(x) + P(x)
= 4x + 350 + 9x - 350
= 13x
Charge per lawn = 
= 
c) For Jimmy to make a profit, P(x) must be greater than zero i.e.
The smallest integer value of x that satisfies this inequality is 39. Therefore, Jimmy needs to mow 39 lawns in order to start making profit.
