When the dimensions of a rectangular prism will be doubled, its volume won't only be doubled but it will be 8 times as much.
The original volume of the rectangular prism is LxWxH.
V= LxWxH
V= (6m) (4m) (10m)
V= 240m³
If we double the dimensions, the volume would be
V= 2L x 2W x 2H
V= 2 x 6m x 2 x 4m x 2 x 10m
V= 2 x 2 x 2 x 6m x 4m x 10m
V= 2³ (6m x 4m x 10m)
V= 2³ x 240m³
V = 8 x 240m³
V= 1920 m³
The new volume now is 1,920 m³, which makes the rectangular prism larger than the original.
Answer:
Option B: 26cm is the radius of smaller circle.
Step-by-step explanation:
Given that:
Ratio of circumferences of two circles = 2:3
We know that circumference of circle is given by 2πr.
Radius of larger circle = 
= 39 cm
Radius of smaller circle = 
Now,
Putting radius of larger circle
Therefore,
The radius of smaller circle is 26cm.
Hence,
Option B: 26cm is the radius of smaller circle.
Answer:
<h2>$205</h2>
Step-by-step explanation:
45 - 25 = 20
65 - 45 = 20
as you can see the common difference between the 3 consecutive numbers 25 , 45 and 65 is a constant (20)
so ,we are in an arithmetic sequence case with :
Let’s label the sequence: Un
then
Un = U1 + (n-1)×r
= 25 + (n-1)×20
= 20n + 5
for n = 10 → U10 = 20(10) + 5 = 200 + 5 = 205
You have to add the first year then for the 2nd year you have to add the estimated difference
28 divided by 4= 7
7-3=4
answer: 4 notebooks left.
