Assuming that you mean (2x8)-1 then the answer is 15m.
Use the fact that the diameter is twice the radius. d = r - 4; replacing for d, 2r = r - 4
A centimeter is less than a meter.
Twice the size
Yes because it is twice the size of the radius.
Greater than 1 meter, as there are 100 cm in 1 meter.
Less. There are 100 centimeters in a meter, so 90 cm would be 10 cm less than a meter.
3 less than twice n is 2n-3
1 yard is a little less than a meter. 1 decimeter = 1/10 meter. 1 centimeter = 1/100 meter, etc.
An average pencil measure approximately 18 cm which is considerably less than 1 meter. a meter is about the length of a yard stick!!
Yes, 5 centimeters is less than a meter. One meter is equivalent to 100 centimeters, so 5 centimeters is significantly smaller than that.
no
Oh, dude, a pencil is definitely less than a meter long. I mean, unless you have some giant novelty pencil or something. But your average, run-of-the-mill pencil? Yeah, definitely shorter than a meter. Like, imagine trying to fit a meter-long pencil in your pencil case. That would be a sight to see.
