Answer:
3052 cm^3 (Answer C)
Step-by-step explanation:
The formula for the circumference of a circle of radius r is C = 2(pi)(r). We know that C = 56.52 cm and want to find the model's radius:
C 56.52 cm
Solving for r, we get ---------- so that in this case r = ------------------ or
2(pi) 6.28
r = 9 cm.
The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r^3), which here comes out to:
V = (4/3)(3.14)(9 cm)^3 = 3052 cm^3 (Answer C)
Answer:
Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi
Step-by-step explanation:
The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
