The formula for surface area is SA=4pi(radius)^2
This means that 4SA=4pi(2r)^2
because 2^2=4
so multiply the first ball's surface area by 4
the answer is c
Answer:
-4 3/4, -4 1/2, -4 1/4
Step-by-step explanation:
Answer:
0 = -10
Step-by-step explanation:
add 9+2=11
11-10=1-10x rearange terms
-10x+11=1-10x subtract 11 from both sides
−10+11−11=−10+1−1
-10x=-10x-10 add 10 to both sides
−10+10=−10−10+10 simplify cause you subtracts 10 from each side and your left with
0=-10
82 cubic feet is the answer
