Answer: 60°
Step-by-step explanation: A straight angle is 180°
180°- 120° = 60°
Answer:
idc its 12
Step-by-step explanation:
Answer:
29.3
Step-by-step explanation:
4x+12+5x+3x-4=360
Add the X's up & move the numbers w/out factors (X's) to the 360 side. This will look like 12x=352
Then, you divide each by 12, leaving you with x=29.3
Might be wrong, let me know and I will rework it.
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
