Answer:
707.9 cm³
Step-by-step explanation:
What is the volume of a spherical shell with inner radius 7 and outer radius 8?
The formula for the volume of a sphere is given as;
= 4/3 × π × r³
From the above question:
inner radius 7 and outer radius 8
Hence, the volume of a sphere with
inner radius 7 and outer radius 8 is calculated as:
V = (4/3 × π × 8³ ) - (4/3 × π × 7³)
V = 4/3 × π ×(8³- 7³)
V = 4/3 × π × (512 - 343)
V = 4/3 × π × 169
V = 707.9055446 cm³
V = 707.9 cm³
The perimeter of the equilateral triangle is 3s and s=4x so the perimeter is:
12x
And we are told that the perimeter of the square is the same. And that perimeter is 4s where s=(x+6) so that perimeter is equal to
4x+24, and again, we are told that these two values are equal so we can solve for x...
12x=4x+24
8x=24
x=3 and if x=3 then the side length is (x+6)=9
So the area of the square is always A=s^2 and s=9 thus:
A=9^2
A=81 u^2
Answer: D
Step-by-step explanation: The others dont have A m or an s
An irrational number is a number than can't be put into a fraction. and is usually REALLY long number with decimal and does not have repeating numbers
A. 3/4 = 0.75 It is a fraction
B. √225 = 15 It is a whole number
C. √17 = 4.1231056245617.... It is an irrational number
D. 175.2845 It is not irrational and can be put into a fraction (
Answer:
51.5 in , Formula: y=1/2x+48
Step-by-step explanation:
First, create a formula as shown above
Next, plug your number into the formula:
y=1/2(7)+48
Then, simplify your equation by multiplying 1/2 by 7 and getting 3.5, now add 48 and you get 51.5in
Last, check your work by adding 1/2 seven times and you will get the same result
I hope this helps you and if it does please give a thanks (i would eternally appreciate a brainliest trying t level up)
