  • Diameter = 51 cm
  • Radius (r) = 51 cm ÷ 2 = 25.5 cm
  • π = 3.14
  • Circumference
  • = 2πr
  • = 2 × 3.14 × 25.5 cm
  • = 160.14 cm
  • Area of a circle
  • = πr^2
  • = 3.14 × (25.5)^2 cm^2
  • = 3.14 × 25.5 × 25.5 cm^2
  • = 2041.785 cm^2

Hope you could understand.

Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours
rusak2 [61]

Answer:

f(w) = 120 + 5(30-h)

Step-by-step explanation:

It is given that, Andrew gets paid $4 for first 30 hours of the week

So,

For first 30 hours, his wage will be:

4(30) = $120

Now, let w denote wages and h denote total number or hours he works in the week

So he will be paid $5 for h-30 hours

So the function will be

f(w) = 120 + 5(30-h)

Where $120 is the fixed income for first 30 hours and the second term is the wage of hours more than 30 at the rate of $5 per hour..

Form the union for the following sets m={} n={6,7,8,9,10}
Levart [38]

Answer:

M\cup N={6,7,8,9,10}.

Step-by-step explanation:

We have an empty set: M={} and the set N={6,7,8,9,10}.

The union of these two sets are elements in M or N or both.

Since the M is a null set, M\cup N=N

Therefore: M\cup N={6,7,8,9,10}.

The union for the given sets is {6,7,8,9,10}.
