Find the area of the shaded region <br>​
tatiyna

Answer:

9.82 inches²

Step-by-step explanation:

both areas are equally sized, so they are both half of the whole circle.

circle area : pi × r²

half of the circle area is therefore pi × r² / 2

the picture gives us the diameter of the circle, the radius is half of the diameter.

=> r = 5/2 = 2.5

=> shaded area = pi × r² / 2 = pi × (2.5)² / 2 = 9.82 inches²

A 450m long field is drawn to a scale 1cm to 90cm.find the lenth of drawing<br><br>​
irina1246 [14]

Answer:

500cm or 5 meters

Step-by-step explanation:

The ratio of drawing and field is 1:90.

So we have to make 450 m into cm.

450 -> is 45,000

Now we can make 2 fractions,

\frac{1}{90}=\frac{x}{45000}

Cross multiply

90*x = 90x

1*45000 = 45000

90x = 45000

Divide 90 to both sides

x = 500cm

<em>Thus,</em>

<em>the drawing's field is 500cm or 5m long.</em>

<em />

<em>Hope this helps :) </em>

Hellp with theseeee pls !! Asappp
Llana [10]

Answer:

a is 60 ft^3 and b is 45

Step-by-step explanation:

b is 45 because 60/4 is 15, which would mean that 4/4 is 60, and since it says 3/4, you subtract 15 from 60 to get 45.

a is 60 because volume equals length times width times height, the three measurements shown

(edit)

and when multiplied you get 60 altogether.
