Answer:
.78
Step-by-step explanation:
3.90/5 = .78
Answer:
2.25 radians
Step-by-step explanation:
First we need to find the length of the circunference, using the formula:
C = 2 * pi * r
Where r is the radius. Using r = 8, we have:
C = 2 * pi * 8 = 50.2655 cm
Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:
2pi rad -> 50.2655 cm
x -> 18 cm
x = 18 * 2pi / 50.2655
x = 2.25 rad
Answer:
282 ft
Step-by-step explanation:
Area of 2 triangles = 6+6
= 12 ft
Area of 3 rectangles = 90+90+90
= 270 ft
therefore
the surface area = 12 + 270
= <u>282 ft</u>

Answer:
P=12, P=8,8, P=4,5
Step-by-step explanation:
P=4*m, P=area
If m=3, P=4*3=12
if m=2,2 P=4*2,2=8,8
if m=1/5 P=4*1/5=4/5
if P=11 then 4*m=11, m=11/4
The area of the rectangle is 11 if m =11/4
