Answer with explanation:
Number of four digit numbers using four distinct digit
=Unit placed can be filled in four ways * Tens place can be filled in Three ways * Hundreds place can be filled in 2 ways * Thousand Place can be filled in a single way
=4*3*2*1
=24 distinct numbers
Sum of all four , four digits numbers using 1,2,3,4
= (If we keep 4 at unit place +Keeping 3 at unit place +Keeping 2 at unit place+Keeping 1 at unit place)×6+At tens place (2*2+3*2+1*2+4*2+2*2+1*2+1*2+3*2+4*2+2*2+3*2+4*2)+At hundred's place (2*2+3*2+1*2+4*2+2*2+1*2+1*2+3*2+4*2+2*2+3*2+4*2)+At thousand's Place(2*2+3*2+1*2+4*2+2*2+1*2+1*2+3*2+4*2+2*2+3*2+4*2)
=(24+18+12+6)Unit place+(60)Ten's place +(60)Hundred's place+(60)Thousand's Place
=66660

Answer:
91.99%
Step-by-step explanation:
To find what percentage of $7599 is $6990, we simply need to divide $7599 by $6990 and multiply by 100:

Answer:
The right answer is A = 49.6 π ft^2
Step-by-step explanation:
<em><u>(Let pi = 3.1415926535898)</u></em>
<em>The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2</em>
<em>So if r = 4 ft</em>
<em>and h = 2.2 ft</em>
<em>A= 2π(4)(2.2)+2π(4)^2</em>
<em>Once we've plugged in our formulas our final surface area is A =</em><em> 49.6 π ft2</em>
