(C.) 4.012
4.021 is greater than 4.012
Answer:
1,080 cm2
Step-by-step explanation:
you need to find the surface area...so
15x12=180
180x4=720
12x12=144
144x2=288
720+288=1008
we are given
geometric sequence -36, 6, -1, 1/6, ...
first term is -36

now, we can find common ratio


now, we can find nth term

now, we can plug values
and we get

now, we can find 5th term , 6th term, 7th term
fifth term:


sixth term:


seventh term:


so, next terms are
, 
,

The surface area of the balloon is 249 in².
<h3>What is the surface area of the balloon ?</h3>
A balloon has the shape of a sphere. The distance round the sphere is equal to the circumference of the sphere.
Circumference of the sphere = 2πr
Where:
- r = radius
- π = pi = 22 / 7
Radius - circumference / 2π
28 / ( 2 x 22/7) = 4.45 inches
Surface area of a sphere = 4πr²
4 x 22/7 x 4.45² = 249 in²
