Answer:9
Step-by-step explanation:
The formula for finding the surface area of a sphere is A=4π

. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x 
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is
12.6.
Hope this helps!

Answer:
£252
Step-by-step explanation:
The ratio of their profit is 9 ; 5 = 9x : 5x ( x is a multiplier )
Bill gets £72 more than Mischa , then
9x = 5x + 72 ( subtract 5x from both sides )
4x = 72 ( divide both sides by 4 )
x = 18
Total received = 9x + 5x = 14x = 14(18) = £252
