Answer:
6,7
Step-by-step explanation:
<em>flat surfaces on a rectangular prism are called faces..
<u>reason:
</u>it is so because those surfaces are of polyhedron shape means that their spherical surfaces are in front and they have a general outward appearance .. Face is a Latin word( facies) meaning
<u>in front...</u>polyhedron shape is like:
</em>
Area = 50.27 ft squared
area of circle = πr^2
a = π(4^2)
a = π16
a = 50.27
π = about 3.14159
3.14159(16) = 50.26544 --> 50.27
Answer:
432 lb
Step-by-step explanation:
Find the area of the first square:
40*50=200ft^2
Find the area of the larger square:
60*90=5400 ft^2
Now divide the larger square area by the smaller square area:
5400/200 =27
27 is the ratio of the difference
27*16=432 lb
