Step-by-step explanation:
perimeter=4×6-1/4 ×2π×3=24-1/2×3.14×3=24-4.71=19.29cm
Answer:
E 60+60+60=180 sum of triangle's angels must be 180
Because it is much easier to identify the place values when multiplying numbers. You can immediately sight the numbers to be multipied.
An example
10
x 5
___
0
Then
5 -0= 50
Answer:
55
Step-by-step explanation:
The first crayon is chosen out of 11,so there are 11 choices
11
The second crayon is chosen out of 10 crayons left so there are 10 choices
10
11*10 = 110
But we do not care about the order, so we divide by 2 since there are 2 places
110/2 =55
Answer:
π/36 sec-1
Step-by-step explanation:
From the question we are given the formula below
s = rwt ..........eqn(1)
Where s= π/3m, r=3 m, t= 4 sec
We were not given value of " w" which implies we are required to find out values of" w"
We can make " w " the subject of the formula from eqn(1)
s = rwt
w= s/(rt)........eqn(2)
Then substitute for the values in eqn(2)
w= (π/3m ) / ( 3m × 4 sec)
= π/36 sec-1
Hence, the value of the
missing variable is π/36 sec-1
