It’s 30 square units cus it’s area and area is Length * Widtj
The volume of the cone by definition is given by:
V = (pi * r ^ 2 * h) / 3
Where,
h: height
r: radio
Substituting the values we have:
V = (pi * (9/2) ^ 2 * (16)) / 3
V = 339.2920066 in ^ 3
Rounding:
V = 339.3 in ^ 3
Answer:
the volume of the cone is:
V = 339.3 in ^ 3
Answer:
So therefore, the diameter is 36 inches
Step-by-step explanation:
first you would divide by 2, which is 56.52
(about) then divide by pi and you get 18.
so multiply 18 by 2 and you get 36.
Answer:
circumference of the cake board = 109.9 cm
Step-by-step explanation:
diameter of cake = 30cm
diameter of cake board = 5cm longer than 30cm = 5 + 30 = 35cm
radius cake board = diameter ÷ 2 = 35 ÷ 2 = 17.5 cm
radius of cake board = 17.5 cm
circumference of a circle = 2 × π × r (where π = 3.14)
circumference of a circle = 2 × 3.14 × 17.5 = 109.9 cm
Therefore the circumference of the cake board = 109.9 cm
Answer: 52 square cm
Step-by-step explanation:
The given surface area formula of a rectangular prism,
S = 2 wl + 2 lh + 2 hw
Where is the length, w is the width and h is the height of the prism,
Here, length, l = 2 cm,
Width, w = 3 cm
And, Height, h = 4 cm
Thus,The required surface area of the prism,
S = 2 × 3 × 2 + 2 × 2 × 4 + 2 × 4 × 3
S = 12 + 16 + 24 = 52 square cm.
