V= pi x r^2 x h
V/(pi x h)=r^2
square root of [V/(pixh)]=r
Answer:
d ≤3
Step-by-step explanation:
9−4d≥−3
Subtract 9 from each side
9-9−4d≥−3-9
−4d≥−12
Divide by -4, remembering to flip the inequality
-4d/-4 ≤-12/-4
d ≤3
Answer:
¹²/₇
Step-by-step explanation:
Model ⁴/₇ × 3
Assume that you have three pies, each dived into seven slices.
There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate
The picture represents ⁴/₇ × 3.
Model the product
Now, transfer slices to get as many filled pie plates as possible.
Count the total slices.
You have 12 slices, and each slice represents ⅐ of a pie.
You have ¹²/₇ pie.
∴ ⁴/₇ × 3 = ¹²/₇
You are given that 1 inch = 2.54 centimeters, so to convert 12.4 inches to centimeters, you would multiply 12.4 in by 2.54 cm.
