Answer: 3x23+b
G67282
Step-by-step explanation:
Answer: 42.14 cm^2
square:
Area of a square=s^2
A=14^2
A=196
circle (the two semi circles are the same as one circle):
Area of a circle=(pi)(r)^2
divide 14 (diameter) by 2 to find the radius
A=(3.14)(7)^2
A=(3.14)(49)
A=153.86
subtract the area of the two semi circles from the area of the square to get the answer
196-153.86=42.14
Hi,
So 50 billion written out would be 50,000,000,000
In scientific notation that would be 5.0 x 10^10
