Its going to be 3/7 because 3 is the first number and 7 is the second
Answer:
C.
Step-by-step explanation:
Area of a Sector Formula: A = x/360πr²
Since we are given <em>x</em> and <em>r</em>, simply plug it in:
A = 40/360π(4)²
A = 1/9π(16)
A = 16π/9
Answer:
So the answer is 12 and 31.
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
As both numbers that were used for estimation are greater than actual numbers the estimated product will be greater than the actual product.
Step-by-step explanation:
Estimation is used to find the product of two large numbers without using any electric device.
In estimation, we take the nearest whole numbers with zeroes so that the multiplication becomes easy.
The given numbers whose product has to be estimated is:
37*86
The numbers used for estimation are
40*90
As
40>37
90>86
As both numbers that were used for estimation are greater than actual numbers the estimated product will be greater than the actual product.
