First we would need the sector formula which is: 丌r^2× angle/360
To find the radius,we would have to divide the diameter by two,which is:
l8÷2=4 units
We would also need to find the total valuenof angles of pink sectors:
41+44+47=132°
As it's not mentioned,let's take pi as 3.14.
In this case,it would be:
(3.14)(4)^2(132°/360°)
=16(3.14)(11/36)
=18.4213..
≈18.4 sq. units
Thus the answer us D.18.4 units.
Hope it helps!
It is 639.5. this is how you round numbers to the nearest tenth:
if the digit in the hundredths place is 5 or more you round up one, if it is lower than 5 it stays the same, pay no attention to the thousandths place....ex--> 0.497
the 4 is the tenths place
th 9 is the hundredths place
the 7 is the thousandths place......since 9 is 5 or more you round the 4 up one number, so the 4 would be a 5. pay no attention to the 7. lets do another
0.426
the 4 stays as a 4 because 2 is a lower number than 5.
15 divided by 2 1/2=6

7x8÷4x37x8÷4x3 = 3108/1 = 3108
