Answer:youre not dum :)
Step-by-step explanation: e
<span>ratio of their perimeters and the ratio of their areas would be </span>5:9 and 25:81
Since there is a 5 to the right of the decimal, you will round the number immediately to the left of the decimal up. So the nearest whole number would be 71.
Answer:
70.622 in³
Step-by-step explanation:
Volume of cylinder = 
= (3.14)(2.1^2)(5.1)
= 70.622 in³
The answers are A and D.
The numbers that you cannot simplify without having a radical in the answer are irrational numbers.
√(4/16) = 1/4 or -1/4, rational number
√(9/16) = 3/4 or -3/4, rational number
√(9/4) = 3/2 or -3/2, rational number
√(3/16) = √(3)/4, NOT a rational number, cannot remove radical
√(3/4) = √(3)/2, NOT a rational number, cannot remove radical
