Answer:
The volume of a right circular cone is .
Step-by-step explanation:
The circumference of the base of a right circular cone is 125.6 ft.
Height of cone is 75 ft.
Circumference of base is :
, r is radius
The volume of a cone is given by :
So, the volume of a right circular cone is .
Answer:2.25cm
Step-by-step explanation: To find the radius of the length, then we are going to have,
Volume of a cylinder=πr^2h
Radius =? H=15cm V=240n cube cm
240ncm^3=3.142×r^2cm×15cm
240cm^3=47.13r^2
The next thing is to divide through by 47.14
r^2=5.09229
Take the square root of both sides, then our answer will be given as;
r=2.25cm
Power rule I believe.
w²w³ = w²⁺³ = w⁵
Answer:
Explanation:
(3/14)k - 1 - 4 - (2/7)k = 0
(3/14)k - (4/14)k - 5 = 0
(-1/14)k = 5
-k = 5 x 14
k = -70
