The answer will be B.251.2
c=2πr
Answer:
D
Step-by-step explanation:
The amount of plastic needed to cover the globe is the surface area of the globe. Since a globe is a sphere, the formula is SA = 4/3 πr³. Substitute r= 3 inches.
SA = 4/3 π(3)³ = 4/3 π * 27 = 36π
Answer:
37.9 degrees
Step-by-step explanation:
Using the law of sines,
. It follows that
. Therefore,
.
The area is one side times the other side
Make the other side x.
12x=42
x=42/12=3.5
The perimeter is 2x+2y where x and y are sides of the rectangle.
P= 2(3.5)+2(12)=7+24=31 inches
Hope this helps.
