The commutative property says that a+b=b+a. Basically the sum is the same no matter the order in which you add the terms.
Final answer: 9+3=12
Answer:
length = 32m, width= 16m
Step-by-step explanation:
l=2w
2(2w+w)=96
2(3w)=96
6w=96,w= 96/6 = 16m
l=2w=2x16=32m
Answer:
The area of remaining sheet is 1077cm²
Step-by-step explanation:
First, you have to find the area of circle using the formula, A = πr², where r is the radius of circle:
r = 20cm
A = π × 20²
= 400π cm²
Second, you have to find the area of rectangle:
A = 12 × 15
= 180 cm²
Lastly, you need to substact the area of rectangle feom the area of circle to find the remaining sheet that has not being cut:
A = 400π - 180
= 1077 cm² (3s.f)
Answer:
The two regular cans of soup has a greater volume than the family size can of soup
Step-by-step explanation:
step 1
Find the volume of two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm
The volume is equal to
![V=2[\pi r^{2} h]](https://tex.z-dn.net/?f=V%3D2%5B%5Cpi%20r%5E%7B2%7D%20h%5D)
we have
----> the radius is half the diameter
substitute
![V=2[\pi (4)^{2} (10)]](https://tex.z-dn.net/?f=V%3D2%5B%5Cpi%20%284%29%5E%7B2%7D%20%2810%29%5D)
step 2
Find the volume of one family can of soup, with a diameter of 10 cm and a height of 12 cm
The volume is equal to
we have
----> the radius is half the diameter
substitute
therefore
Compare the volumes
The two regular cans of soup has a greater volume than the family size can of soup
