Answer:
The spinner travelled 94.2 inches.
Step-by-step explanation:
In order to solve this question we first need to calculate the length of the circle, that is given by the following formula:
length = 2*pi*r
length = 2*3.14*3 = 18.84 inches
Since the spinner revolved around the circle 5 times, the distance travelled by the tip is the length of the circle multiplied by 5, as shown below:
distance = length*5
distance = 18.84*5 = 94.2 inches
The spinner travelled 94.2 inches.
These words are represented as homophones as they sound alike but have the different meanings.
Answer:
degree = 120°
A =67 cm²
d=?
note : diameter= 2×radius
area of a circle = πr²
67=22/7 ×r²
67×7=22r²
469=22r²
r²=469/22
r²=21.32
r=4.62
diameter=2 × radius
d= 2× 4.62
d=9.24
d=9
I hope it helps :)
Answer:
x=18
Step-by-step explanation:
ok, so you mulityply base and hieght then divide by 2
your base is 6 and your height is 6
6x6=36
36/2=18
your welcome

Answer:
Cos(x+x)=cosx*cosx-sinx*sinx
=cos2(x)-sin2(x)
=(cosx+sinx)(cosx-sinx)
