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

Answer:
Step-by-step explanation:
the given figure is rectangle
area of rectangle=l*b
=5*6
=30 ft^2
Step-by-step explanation:
Key : Plug in the numbers given in the parenthesis into the x values of the corresponding functions.
f(1/2) = 1/ 1/2 - 4 = 1/-7/2 = -2/7
g(1/2) = 1/1/2 - 2 = -3/2
f(-1/4) = 1/-1/4-4 = 1/-17/4 = -4/17
g(-1/4) = 1/-1/4 - 2 = 1/-9/2 = -2/9
Answer:
Neither
Step-by-step explanation:
To be parallel the lines have to have the same slope. In this case the slopes are not the same.
To be perpendicular, the lines have to have negative reciprocal slopes.
For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.
So, the lines are no parallel and no perpendicular.
