The volume of pyramid B would be 8 times larger than pyramid A.
Answer:
12
Step by Step Explanation:
f(n+1) = 2f(n) + 10
a = 2, k = 10
a + k = 2 + 10 = 12
Answer: 24cm
Step-by-step explanation:
Inradius = r
c = the hypothenuse
a & b = the other 2 sides of the triangle
Inradius formula: r = 1/2 * (a+b-c)
Plug in what we know.
2 = 1/2 * (a+b-10)
Multiply both sides by 2.
2*2 = 1/2 * (a+b-10) * 2
4 = a+b-10
Add 10 to both sides.
4+10 = a+b-10+10
14 = a+b
Perimeter formula: P=a+b+c
Plug in what we know
(remember a+b=14).
P=14 + 10
P = 24
