Answer: $15
Step-by-step explanation:
-$50 + $75 = $15
To look for the area of a sector of a circle, the following formula is used:
Area = ( n / 360 ) * pi * r^2
Where: n = measure of arc in degrees
pi = 3.1416
r = radius
Since we are already given all of the needed parts of the formula, direct substitution is done, as shown below:
Area = ( n / 360 <span>) * pi * r^2
</span>Area = ( 45 / 360 ) *3.1416 * (8)^2
Area = 25.133 in^2
Therefore, the area of the sector of the circle is 25.133 sq. in.
Answer: 1221
Step-by-step explanation:
Given : A 4-digit number is a palindrome .
If it has remainder 21 when you divide it by 100, then last two digits are 21.
So required palindrome = _ _ 21
since palindrome does not change if you write it backwards, so first two numbers should be reverse of 21 = 12
hence, the complete palindrome = 1221
So the number is 1221.
