Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
Answer:
32 seconds
Step-by-step explanation:
first 8 secknds gives us the value of set 2.5l
2.5L to make 10 =
10÷2.5=4
That said 2.5L fills 1pL by 4 giving us;
4×2.5= 10L
70000- ten thousand
8000- thousand
000- hundred
00- tens
0- ones
so look at the 7 and if the number on the right is more than 4 you give the ten thousand a new number ; 80000
