Answer:
area= 78.5 cm²
circumference= 31.4 cm
Step-by-step explanation:
Given that the radius is 5cm, r= 5. Substitute r= 5 and π as 3.14 into the equation:
Area of circle
= 3.14(5²)
= 78.5 cm²
Circumference of circle
= 2(3.14)(5)
= 31.4 cm

Answer:
The ordered pair (-6, -1) is the only solution.
Step-by-step explanation:
-6x + y = 35
Let's plug in the points.
(-1, -7) --> -6(-1) - 7 = 6 - 7 = -1 which does not equal 35
(-6, -1) --> -6(-6) -1 = 35
(-1, -6) --> -6(-1) - 6 = 0 which does not equal 35
(-7, -1) --> -6(-7) - 1 = 41 which does not equal 35
Answer:
200ft^2
Step-by-step explanation:
From the first sentence;
L = 2B
Perimeter of a rectangle = 60ft
P = 2[ L +B ]
substitute as follows;
60 = 2( 2B + B)
60 = 2(3B)
60 = 6B
B = 10ft
To find L
L = 2B
L = 2*10
L = 20 ft
Area of a rectangle = LB
= 20×10
=200ft^2
Answer:
y=2x
Step-by-step explanation:
compute the slope first-
(-2,1) and (2,9)
m = 9-1/2-(-2) = 8/2+2= 8/4 = 2
knowing the slope take a given point and substitute it's x and y values into the equation to solve for 'b' the y-intercept-
y = mx + b,
1 = 2(-2) + b,
1 = -4+ b,
b = 5
our equation is y = 2x + 5
if you want an equation parallel to the line it has to have the same slope. Take y = 2x
