Answer:
40%
Step-by-step explanation:
1299-725= 574
574/1299 x 100 = 44.19%
Answer:
<u><em>30cm</em></u>
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
<u><em>Hence the perimeter of the resulting triangle= 10+10+10= 30cm</em></u>
Answer: 5.14 cu in
Step-by-step explanation:
1/2 (π × d) + d, where d is the diameter of the semi
Perimeter = 1/2 (3.14 x 2) + 2
= 1/2 * 6.28 + 2
= 3.14 + 2
Answer:
381.51 in^3
Step-by-step explanation:
Volume of a sphere = 4/3 x pi x r^3
r = 9/2 = 4.5
4/3 x 3.14 x 4.5^3 = 381.51 in^3
Answer:
<h2><em><u>
3.24</u></em> </h2>
<em><u>= yes, because the sqrt of 3.24 is 1.8</u></em>
<h2><em><u>
20.25</u></em></h2><h3>= yes, because the sqrt of 20.25 is 4.5</h3>
