10.4 - 2 = 8.4
1/4(8.4) = 2.1........2 + 2.1 = 4.1 <==
Answer:
Diameter is equal to 38 cm.
Step-by-step explanation:
We know that the circumference equals πd (where d is the diameter).
If we round the value of π to 3.14 then we will get...
πd = 119.32
(3.14)d = 119.32
d = 119.32 / 3.14
d = 38 cm
Therefore the diameter is equal to 38 cm
Area is 6000 yd2
LW = 6000
field must be 40 yards longer than its width
L = W + 40
Replace L with W+40 in 1st equation to solve for Width
(W+40)(W) = 6000
W2 + 40W - 6000 = 0
This is a quadratic but is factorable
Factors of -6000 that add to 40 are (100)(-60)
(W+100)(W-60) = 0
W = -100 or W = 60
Since the width will not be negative discard -100
The width is 60 yards
Length is W+40 = 100 yards
313,626 = 2 * 152,346 + 8934
152,346 = 17 * 8,934 + 468
8,934 = 19 * 468 + 42
468 = 11 * 42 + 6
6 divides 42, so the GCD of 313,626 and 152,346 is 6.
