Answer:
since there are an even number of negatives, just ignore them and multiply normally. 2 x 2=4
4 x 2=8
8 x 2=16
The answer is 16
Question 7:
Diameter = 6.2 cm so Radius = 3.1 cm
A=πr² = 3.14 × 3.1² = 30.1754 cm² = 30.18 cm²
Question 8:
Circumference = 2πr
16π = 2πr
therefore 16 = 2r so r = 8cm
Answer:
???? did u type it correctly?
The easier way to multiply 2/15 by 3/20 will simply be by multiplying the numerators and denominators.
In order to multiply 2/15 x 3/20, we can simply multiply the numerator and the denominator. This will be
= 2/15 × 3/20
= 6/300
= 1/50
Also, in order to multiply the fractions, we can change them to decimal first. This will be:
= 2/15 × 3/20
= 0.133 × 0.15
= 0.01995
In conclusion, multiplying the numerators and denominators is easier and faster.

Check the picture below.
so... you can pretty much see how long RS and QT are, you can just count the units off the grid.
now, let's find QR's length

and let's also find the length for ST

so, add the lengths of all sides, and that's the perimeter of the trapezoid.
