Answer:
13.60
Step-by-step explanation:
use Pythagoras theorem
it is c²=a²+b²
c is hypotenus which is the longest side of a right angle triangle
--->now just put 8 on a and 11 on b
this gives us
c²= 8²+11²
c²= under the root 185
c² = 13.60147051
nearest hundredth is 13.60
hope you understood :)
Answer:
x = 13.60
Step-by-step explanation:
since it is a right angled triangle , we can use pythagoras theorem ,
hypotenuse^2 = base^2 + perpendicular^2
hypotenuse is the side opposite to the right angle .so here,
H = x .you can take base as 11 and perpendicular as 8
h^2 = p^2 + b^2
x^2 = 8^2 + 11^2
x^2 = 64 + 121
x =
x = 13.60

Answer:
Volume = 1114.1
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by:
where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).
Then the square base of the pyramid has an area given by:
Finally,we can now write the volume of the pyramid as:
Rounding the answer to a tenth of a cubic inch, we get:
Volume = 1114.1
