Circumference of a sphere: 2 * pi * r
8 / 2 = 4
r = 4
surface area of a sphere: 4 * pi * r^2
4 * pi * 4^2
4 * pi * 16
64pi

<u>Answer:</u>
The answer is c = 
<u>Solution:</u>
When a sum of two numbers is multiplied by a number, the number can be distributed to the addends separately, then adding the products together will produce the same result as multiplying sum by the number. This property is called distributive property of multiplication.
To find the value of, a(c-b)=d
On applying the distributive property of multiplication which is ![[a\times(b+c)=a\times b+a\times c]](https://tex.z-dn.net/?f=%5Ba%5Ctimes%28b%2Bc%29%3Da%5Ctimes%20b%2Ba%5Ctimes%20c%5D)
Here we get,

So the equation will be,
