Answer:

=28.3m

Step-by-step explanation:

Circumference of a circle = 2πr

Where π= 3.142

From the diagram diameter = 9m

Radius = diameter/2

R = 9/2

R = 4.5m

Circumference = 2×3.142×4.5

Circumference = 28.278

=28.3m

Machine A can produce 435 widget in 3 hours. At this rate how many widget can machine A produce in 7 hours?
Vesna [10]

Answer:

1015 widgets

Step-by-step explanation:

First investigate how many widgets can machine A produce in 1 hour:

If it produces 435 in 3 hours, then it will produce one third of that in one hour:

In ONE (1) hour \frac{435}{3} = 145 widgets

Therefore in seven (7) hours it will produce seven times the amount it does in one hour, that is:

145 * 7 = 1015 widgets
