1.2 times is also 120 percent
Answer:
If you have to share 2 by 3 equally then that is saying divide, when you divide you get .6666 but if you turn it into a fraction it 2 over 3
251.2 =
(3.14)(r^2)(15)
251.2 =
(47.1) (r^2)
251.2 = (15.7)(r^2)
251.2 ÷ 15.7 = 16 15.7 ÷ 15.7 = 1
16 ≈ r^2
4 ≈ r
Answer: the radius is 4 inches
Answer:
83.79 cm²
Step-by-step explanation:
(please refer to attached)
recall that the volume of a cone is given by
V = (1/3) π r² h
where
r = radius = given as 4 cm
h = height = given as 5 cm
assume π = 3.142
substituting the values into the formula:
V = (1/3) π r² h
V = (1/3) (3.14) (4)² (5)
V = 83.79 cm²
