Answer:
2(21/pi)=d
Step-by-step explanation:
The formula for a circumference is C=2(pi)(r) in this case we know our circumference is 42 meters so 42=2(pi)(r), we must leave our radius by itself so we divide by 2 to get 21=pi(r) we then also divide by pi which will get us 21/pi=r and we know that the diameter is double of the radius so we just double which will then be 2(21/pi)=d
There isn't one. Just because you have one name doesn't mean it determines how tall you'll be.
Answer:
Step-by-step explanation:
number of ways=12c2×10c2
1/2 of the books are science books because once you convert the other two books you get 2/6 +1/6= 1/2 so the science books will be the other half.
70.100
the tenth in this number is the one after the decimal point. if the number after the number you are rounding(4) is greater than or is 5 the number you are rounding goes up. if its lower than 5 the number you are rounding stays the same.
