Answer:
=78.5cm
Step-by-step explanation:
pi=3.14
formula=3.14×r×r
3.14×5×5
78.5
Answer:
the answer is 60 inches
Step-by-step explanation:
you have to subtract the perimeter and the numbers that are shown after you add them
238-118= 120 then you have to divide that in half wich =60.
so (A)= to 60 inches.
Answer:
a. (2,5)
b. (14,15.5)
Step-by-step explanation:
a.
y=4x-3
y=-2x+9
Set both equations equal to each other to solve for x.
4x-3=-2x+9
6x=12
x=2
Plug in x to solve for y.
y=4x-3
y=4(2)-3
y=8-3
y=5
(2,5)
b.
y=(5/4x)-2
y=(-1/4x)+19
Set both equations equal to each other to solve for x.
(5/4x)-2=(-1/4x)+19
4((5/4x)-2=(-1/4x)+19)
5x-8=-x+76
6x=84
x=14
Plug in x to solve for y.
y=(5/4x)-2
y=(5/4(14))-2
y=17.5-2
y=15.5
(14,15.5)
Answer: The formula for calculating the circumference is C = pie(d)
or you could also use C = 2(pi)r squared.
side = 8 m
the area of the rectangle = length × width = 16 × 4 = 64 m²
the area of the square = s² ( where s is the length of a side ), hence
s² = 64 ( since areas are equal )
take the square root of both sides
s = √64 = 8 m
