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:
minus 15 by 4
Step-by-step explanation:
minus 9 by 4 minus 3 by 2 lcm then add
No.
4 yards is not greater than 13 ft.
One method that I use often is to bounce the decimal point over and multiply by 2. ex/ total is 23.52, bounce the decimal between the 2 and 3 to get 2.30 then multiply by 2 giving you 4.60.
or take the total 23.52 and multiply it by .20 which will give you 4.70
