Answer: Not rounded: 39.6 Rounded: 40
Step-by-step explanation:
Area of a rectangle: Length x Width
Areas of the rectangular container : 20cm x 16cm , which is 320cm^2
If the rock caused the container to rise 1.5cm, then the volume of the rock will be 1.5cm x the area of the container:
320cm^2 x 1.5cm = 480cm^3
Answer: 480cm^3
25 pi
Step-by-step explanation:
If the circumference equals 10pi
And to calculate the circumference is pi multiplied by diameter then the diameter must be 10
The radius is half the diameter so it is 5
To calculate the radius, you have to multiply pi by the radius squared
Which is pi × 5^2
So the answer is 25 × pi
And simply put : 25pi
