Luckily for us, the diagram already divided this figure into separate polygons. What I will be explaining is basically the addition of the areas of all the separate polygons. The area of the uppermost triangle is:
1/2 x b x h
= 1/2 x 20 x 8
(the base is 20, because in a parallelogram, opposite sides are congruent)
=10 x 8
= 80 in. squared
The next polygon we will be taking the area of is the parallelogram with the base length of 20 and the height of 16.
Area = b x h
= 20 x 16
= 320 in. squared
Now all we have left to do is add the two areas to obtain the total area.
Total Area = 320 + 80 = 400 in. squared
Answer:
210 pounds
Step-by-step explanation:
First, we are going to find the exchange rate from dollars to pounds.
We know form our problem that 800 dollars are 560 pounds. so:
\frac{560pounds}{800dollars} =0.7
800dollars
560pounds
=0.7 pounds per dollar.
Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:
300dollars*\frac{0.7pounds}{dollar} =210pounds300dollars∗
dollar
0.7pounds
=210pounds
We will get 210 pounds for 300 dollars
Answer:
no
Step-by-step explanation:
111 divided by 11 is 10.0909090909
and 88 divided by 8 is 11 so no it`s not proportional.
45° is exactly 1/8 of a full circle (45/360 = 1/8) <span>
So the length of the arc would be 1/8 of a full circumference:
C = 2π r
C = 2π(8)
C = 16π
Take 1/8 of this:
1/8C = (1/8)16π = 2π
Answer:
Exact answer --> 2π inches
(Approx. answer --> 6.28 inches)</span>
