Answer:
x=3, y=4
Step-by-step explanation:
If your in algebra 1 then i'm pretty sure you subtract the 2x and that cancels and subract the 2x with the 9 and you have -3y= -2x+9 so you divide -3 to the -3y, the -2x and positive 9 and your answer will be y=2/3x-3
Answer:
x = 61
Step-by-step explanation:
thats a right angle ,
90 - 29 = 61
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
