Answers found through estimating will vary because people choose to estimate in different ways.
One way to estimate this answer would be to approximate it by 3 x 50.
3 x 50 = 150 so an estimate of 3 x 46 would be approximately (but a little less than) 150.

The factors of 138 are 1, 2, 3, 6, 23, 46, 69, and 138, so the numbers that multiply to produce the product 138 are 1 x 138, 2 x 69, 3 x 46, 2 x 3 x 23, and 6 x 23.

The numbers '1' and '23' evenly divide both 23 and 46.
((4)2)3 simplifies to 46 (Simply multiply the two exponents when they are 'stacked'. 46=4*4*4*4*4*4=4096.

To estimate the circumference, multiply the diameter by 3. If you have a calculator or are decent at multiplication and have the time, multiply it by 3.14. If you can, multiply it by pi.
46
.666666666666... is the same as 2/3. So, you could write it as 46 2/3. If you multiply 46 by 3, you can see that 46 is equal to 138/3. If you add 138/3 and 2/3, you can see that 46.66666666666666... is the same thing as 140/3, so that is your answer.
How about: 2*23 = 46 as a product of its prime factors
Just look at it clearly keep a ruler and works doneTo estimate multiply diameter by 3 and add 15% ormultiply the diameter by 22 and divide that by 7.Just multiply the diameter by 3 for a good estimation.

You multiply the two numbers: 8,300 multiplied by 46 is 381,800.
No, because there is no number u can multiply by 4 to get the result of 46.
