Answer:
31.4 in.
Step-by-step explanation:
The perimeter of a square is
P = 4s,
where s is the length of a side.
P = 4s
40 in. = 4s
s = 10 in.
Each side of the square measures 10 in.
The largest circle that fits inside a 10-square has a diameter of 10 inches.
For a circle, the circumference is
C = πd,
where d = diameter
C = πd
C = 3.14 * 10 in.
C = 31.4 in.
Answer:
x = 80
Step-by-step explanation:
Total = 360
90 + 50 + 90 + 50 = 280
360 -280 = 80
Which product is irrational?
B. √2./8
All the other options are terminating decimals, which means decimals that do not go on forever, these are rational numbers.
Answer:
50 =c×d
Step-by-step explanation:
Substitute (-4, 3) into the equation of curve
3 = 16a - 4b - 13
4a - b = 4
b = 4 - 4a ---- (1)
dy/dx = 2ax + b
At (-4, 3), dy/dx = 0
-8a + b = 0
b = 8a ---- (2)
Fom (1) and (2),
4 - 4a = 8a
4 = 12a
a = 1/3
b = 8/3.
