Answer:
a) 301.6 cm³
b) 188.5 cm²
Step-by-step explanation:
The volume and lateral surface area of the cone can be found using the given dimensions with the given formulas. All that is needed is to substitute the appropriate values and do the arithmetic.
__
<h3>a) volume</h3>
The volume is given by the formula ...
V = 1/3πr²h
The dimensions are given on the diagram: r = 6 cm, h = 8 cm. Using these values in the formula, we find the volume to be ...
V = 1/3π(6 cm)²(8 cm) = 96π cm³ ≈ 301.6 cm³
The volume of the cone is about 301.6 cm³.
__
<h3>b) area</h3>
The lateral area of the cone is given by the formula ...
A = πrl
The dimensions are given on the diagram: r = 6 cm, l = 10 cm (the slant height). Using these values in the formula, we find the area to be ...
A = π(6 cm)(10 cm) = 60π cm² ≈ 188.5 cm²
The area of the curved surface is about 188.5 cm².
Answer: No, you line up the numbers by the decimal making 10.03 larger than 1.904
Answer:
28.75 m.
Step-by-step explanation:
It is given that a ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. So,
For first bounce the vertical distance
For next bounce ball has to travel up and down by 50% of previous distance, i.e., 10 m.
For second bounce the vertical distance
Similarly,
For third bounce the vertical distance
For fourth bounce the vertical distance
For fifth bounce the vertical distance
The total vertical distance down the ball has traveled when it hits the the 5th time is
Therefore, the total vertical distance down the ball has traveled when it hits the the 5th time is 28.75 m.
