Answer:

Step-by-step explanation:

radius of circle=4

diameter=4×2=8

width=2 half circles means diameter=8

length=2 diameters=2×8=16

area=16×8=128

4 half circles make two circles

area of two circles=2×π r^2=2×π×4²=32 π

reqd . area=128-32 π=32(4-π)

Answer:

3.43 hours

Step-by-step explanation:

A castle has to be guarded 24 hours a day. 7 knights are ordered to split each day guard duty equally. How long will each knight spend on guard duty in one day?

From the above question:

7 knights = 24 hours

1 knight = x hours

Cross Multiply

7 knights × x hours = 1 knight × 24 hours

x hours = 1 knight × 24 hours/ 7 knights

x hours = 3.4285714286 hours

Approximately = 3.43 hours

Therefore, each knight would spend 3.43 hours on guard duty in one day

Solve for x. use the completing the square method.<br><br>x^2+8x=5

jok3333 [9.3K]

$x^2+8x=5$

$x^2+8x + ( \frac{8}{2} )^2 =5 + (\frac{8}{2} )^2$

$x^2+8x + (4)^2 =5 + (4)^2$

$(x+ 4)^2 =21$

$x+ 4 = \pm \sqrt{21}$

$x = \sqrt{21} - 4 \ or \ x= -\sqrt{21} - 4$

$x = 0.58 \ or \ x= -8.58$
