Answer:
36
Step-by-step explanation:
If sh missed 8, then 8/2 is 4, 4x9 is 36
Answer: 12πins.
Step-by-step explanation:
Since the area if a circle = πr²
From the question
Area of the circle = 36πins²
To find the circumference of the circle, we need to find the common radius of the circle and this could be achieved from the area of the circle given above.
πr² = 36π, solving this gives. Divide through by π
r² = 36
r = +/-√36
= +/-6
Now to find the circumference of the circle, we substitute for r in the formula below.
Circumstances = 2πr
= 2 ×π × 6
= 12πins.
<span>In our equations, you can use the generic form of y = mx + b to determine the y-intercept for the function, with b equal to the y-intercept. For g(x), b =2 and for f(x), b=-1. These values are the y-intercepts for the functions. Based on this, the y-intercept of f(x) is 3 units below the y-intercept of g(x). We know this because we can subtract the b value from f(x) from g(x) to get the difference. Difference = 2 - (-1) = 3.</span>
Decimal points must be aligned with performing addition or subtraction.
The arithmetic operation that does <em>not</em> require decimal points be aligned is multiplication.
_____
For multiplication, you only need to know the number of digits to the right of the decimal point(s).
For long division, it is usually convenient to convert the divisor to an integer and adjust the decimal point of the dividend accordingly. Alternatively, it is necessary to know the number of digits in each number that are to the left of the decimal point.
