The spray from a lawn sprinkler makes a circle 40 feel in radius. What are the approximate diameter, circumference, and area of

the circle of lawn watered
Mathematics

Fittoniya [83]3 years ago

Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.

Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.

Circumference = 2 * pi * radius = 80 ft * pi 
If we say that pi = 3.14, then:
circumference = 251.2 ft.

Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.

What is the simultanous equation of 2x+y=–5 3x+2y=–8 equation Using the Substitution method​
Artyom0805 [142]

Answer: Equation form: x=-2,y=-1

Point form: (-2, -1)

Step-by-step explanation:

y=-\frac{3x}{2} -4

y=-2x-5

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Solve by Substitution ---> 2x+y=-5 3x+2y=-8

a = 34.64 m²

Paint needed

p = 34.64 / 8

p = 4.33

Must round up

p = 5 liters

Tins needed

t = 5/2

t = 2.5

must round up

t = 3

Cost

since 1 is free with 2 will pay for 2

c = 11 * 2

c = 22
