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
A) 1.443

÷you need to find how many parts there are ; 4 + 3 = <u>7</u>
you then need to divide the number by the parts ; £56 ÷ 7 = <u>£8</u>
<u />1 part = <u>£8</u>
<u />4:3, 4 parts : 3 parts.
4 x £8 = <u>£32</u>
3 x £8 = <u>£24</u>
<u><em /></u><em> <u>4:3</u></em><u /><u /> = <em><u>£32:£24</u></em>
<em>to check your answer ;</em>
<em>add both parts of your final answer , £32 + £24 = <u>£56</u></em><u><em></em></u>
Answer:
i just know is not a function
