Step-by-step explanation:
the common ratio of the geometric sequence 4, -12,36,...
= -12/4 = -3
That's what I got I think it's correct
We gots triangle and half circle
square is meaning all sides are 20
that means height and base are 20 (isocelese)
and diameter is 20
area triangle=1/2bh=1/2(20)(20)=200
square=side*side=20*20=400
semicircle=1/2*pir^2
d/2=r, 20/2=r=10
semi=1/2*pi*10^2=1/2*pi*100=50*pi
using aprox pi=3.141592
semi=157
add them all
200+400+157=757
G is answer
Question :
Cone is formed from 3200 ft³ of gravel, if the height of the cone is 24 ft what is the radius in feet of the base of the cone
Answer:
11.3 feet
Step-by-step explanation:
The volume of a cone = πr²h/3
We are asked to find the radius
The formula is given as:
r = √3V/πh
V = 3200 ft³
h = 24 ft
r = √3 × 2400/π × 24
r = 11.28379 ft
Approximately = 11.3 ft
The radius in feet = 11.3 ft
