A circle has its center at the center of a square with 26-inch sides. Using 3.14 for pi, find the area of the square not covered
AlladinOne [14]
For squrae
area=side²
perimiter=4(side)

for circle
area=pir²
circumference=2pir

side=diameter, diameter/2=radius=side/2


find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches

areanotcovered=676-530.66=145.34 square inches not coverd


ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785

What's -2x-8y=12 in y intercept form
Free_Kalibri [48]
Y=2/-8x-1.5 ( pretty much add 2x to both sides, then divide all parts by negative 8. So it'd be 2 over -8 and then 12 divided by -8 which equals -1.5)

dem82 [27]

Answer:

a) 0.6435 radians

b) 80.1 feet/sec

Step-by-step explanation:

a) 75 = (50²/16)sin(theta)cos(theta)

sin(theta)cos(theta) = 0.48

2sin(theta)cos(theta) = 0.96

sin(2theta) = 0.96

2theta = 1.287002218

Theta = 0.6435011088 radians

b) 200 = (v²/16)sin(0.75)cos(0.75)

6416.072347 = v²

v = 80.10038918 feet/sec
