Find the area of the circle.
S_A_V [24]

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

Jimmy decides to mow lawns to earn money. The initial cost of his electric lawnmower is ​$350. Electricity and maintenance costs
hodyreva [135]

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 = \frac{\text{Revenue}}{\text{Number of lawns}}

= \frac{13x}{13} = \$13

c) For Jimmy to make a profit, P(x) must be greater than zero i.e.

P(x) >0

9x-350 >0

9x >350

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.
