1/2= 50%
2/5=40% is the answer
Answer:
c=20 or SU = 20
Step-by-step explanation:
I'M HURRRRYYYINNNNNG DON'TT WORRY!!! :D
Use the Pythagorean theorem:
a²+b²=c²
Plug it in:
12²+16²=c²
144+256=400
c²=400
c=√400
c=20
There did i finish on time!!? XD
The general formula for the sum of the n terms of a geometric progression is:
Sn = A1 (1 - r^n) / (1 - r)
In this case, n = 8; A1 = - 11, r = -4
S8 = -11 (1 - (-4)^8) / (1 -(-4)) = 144,177
Answer: option c.
Answer:
34072.3 in³
Step-by-step explanation:
Step 1
The circumference of its base is 125.6 inches.
C= pi x diameter
Find the radius of the base
C/ π = Diameter
Diameter = 125.6 in/2
= 62.8 in
Step 2
The height of the cone is 33 inches.
Radius = Diameter/2
Radius = 62.8 in/2
= 31.4 in
Volume of a cone: V = (1/3)πr²h
= 1/3 × π × (31.4)² × 33
= 34072.33162 in³
Approximately = 34072.3 in³
Therefore, the volume of Nuala's cone is 34072.3 in³.
