Answer:
the awnser is 8/15 because of 5+3=8
Step-by-step explanation:
5+7+3=15
8/15
the shape is a pyramid which means theres 4 triangles (all are equal) and a square at the bottom
Tringle area: 1/2bh
1/2(4)*5=10
area of triangle is 10m
Square area: bh
4*4=16
area of square 16m
surface area:
4(10)+16= 56
surface area: 56m
Answer:
google SA of a pyramid and fill it out
Step-by-step explanation:
Answer:
Divide the diameter by 2.
Step-by-step explanation:
A. 15.9ft
B. 24.84ft
C. 31.8ft
D. 11.73ft
Answer:
C. 31.8ft
Step-by-step explanation:
Perimeter of a parallelogram is calculated by this formula P = 2(a+b) (b: base, a: side)
The base given here is 10.8 ft and side is 5.1 ft
2 × (5.1+10.8) = 31.8 ft
Answer:
B) 24.84.
Step-by-step explanation:
Its hard to explain but ===>
First do Pythagorean theorem with 2.3 and 5.1.
You will need to do two thing with that answer.
First subtract it from the 10.8. That will be used for later.
Also, multiply it by 2.3 that is for the triangles that are on the sides.
Next you will want to take the number you set aside and multiply it by 2.3.
Finally add and you will have your answer.
