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:
A and D represent linear functions
Answer:
No, because the cone has a smaller volume than the ice cream
Step-by-step explanation:
V=4
3πr3=4
3·π·33≈113.09734
Volume of scoop: 113.1 cm^2
V=πr2h
3=π·2.52·10
3≈65.44985
Volume of cone: 65.45 cm^2
65.45 < 113.1
Answer:
1.2 + 2.3
Step-by-step explanation:
Answer:
y=124°
x=67°
Step-by-step explanation:
For the triangle on the right
180-74-50=56°
then y= 180-56=124°
For the triangle on the middle (that small triangle)
180-85(Head opposite angles)-50=45°
So
x=180-45-68=67°
