The approximate surface area of the balloon is 199 cm².
The approximate volume of the balloon is 262 cm³
<h3>What is the surface area and the volume of the balloon? </h3>
Radius of the balloon = circumference / 6.2832
25 / 6.2832 = 3.98cm
Surface area = 4πr²
4 x 22/7 x 3.97² = 199 cm²
Volume = 4/3πr³
4/3 x 22/7 x 3.97³ = 262.20 cm³

Answer:
x = 30
m<Y = 60
m<Z = 60
m<X = 60
Step-by-step explanation:
All of this should add up to 180 so...
2x + 2x + 3x - 30 = 180 (collect like terms)
7x - 30 = 180 (add 30 on both sides)
7x = 210 (divide by 7 on both sides)
x = 30
PLUG IN
2(30) = 60
3(30) - 30
90 - 30 = 60
m<Y = 60
m<Z = 60
m<X = 60
