Answer:
7.5cm²
Complete question:What is the surface area of the 8-sided figure?
Step-by-step explanation:
Consider the half of the 8-sided die i.e the pyramid ABCDE:
As the base is 6 of the perimeter, so each side of the base is 6/4=3/2
Now, the distance between the tallest points is 2 cm, so the height of Pyramid ABCDE is 1 cm.
Considering the right triangle EOM:
EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is

5. So side EBC has area

6. The total area is 8*Area(EBC)=
Answer:6 billion
Step-by-step explanation:
Just multiple both numbers
Answer:
f¹⁶
Step-by-step explanation:
f³*f⁹*f⁴
f⁽³⁺⁹⁺⁴⁾
f¹⁶

A standard approach would be the tangent half-angle substitution:

Then


from which we get

So the integral becomes

Rewrite the denominator as

and expand the integrand into its partial fractions:

We have
