Answer:
About 24.4
Step-by-step explanation:
Answer:
90.3125 cm³
Step-by-step explanation:
Since the perimeter of the bottom square is 17, you can divide by four to find out what the lenght of each side is.
17/4=4.25 cm
We know the height of pyramid is 15 cm
The formula for the volume of a square pyramid is
V=a²(h/3)
V=a2(h/3)=4.252·15/3=90.3125 cm³
N(4)-1
n(4)-2
ex 2(4)=8
8-1=7
7(4)=28
28-2=26
so the next number would be 1595
Answer:
168 miles
Step-by-step explanation:
Answer:
95
Step-by-step explanation:
First, find the area of the 4 triangles:
a= 1/2 base times height
a=(1/2)(5)(7)
a= 17.5
17.5 times 4 = 70 (4 triangles)
Now find the area of the square:
a=5 times 5
a=25
add: 70+25 = 95
