Its in the tens place so the unit value is 30
First the 2 bases have surface area pi*1.25^2*2
Then the side
2.5pi*4=10pi
total of 9.817+31.415
=41.232
This approximation could be further round down for this problem to 41.2
Which makes choice C the correct choice.
Answer:
8m
Step-by-step explanation:
The area of a square is length*width.
We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.
=8
One side is <u>8m</u>.
If you cross mulitply the answer would be 13.3
Answer:
∠ A ≈ 44.42°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos A =
=
=
, then
∠ A =
(
) ≈ 44.42° ( to the nearest hundredth )
