So you need to find the volume for the rectangular prism (1) and the rectangular prism in the center of it (2)
The formula for a rectangular prism is:
V = lwh [Volume = length x width x height]
1.
l = 15
w = 6
h = 6
V = lwh Plug in the numbers
V = (15)(6)(6) = 540
2.
l = 15
w = 4
h = 4
V = lwh
V = (15)(4)(4) = 240
Next you subtract the volumes by each other because the rectangular prism in the center(2) is the hole/empty part of the rectangular prism(1)
V = V(1) - V(2)
V = 540 - 240
V = 300
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
638272 is the radius I think
Answer:
Step-by-step explanation:
x² = 80² + 39²
x² = 6400 + 1521
x² = 7921
x = 89 inches
