Given:

The radius of the base = 3 cm

The height of the cone = 8cm

To find:

The volume of the cone

Step-by-step solution:

The volume of the cone = 1/3 × πr²h

The volume of the cone = 1/3 × 3.14 × (3)² × 8

The volume of the cone = 3.14 × 3 × 8

The volume of the cone = 75.36 cm³

Thus we can s

Anit [1.1K]

Answer:

4.72 hours/day

Step-by-step explanation:

Mean time spent watching TV (μ) = 2.8 hours a day

Standard deviation (σ) = 1.5 hours a day

The 90th percentile (upper 10%) of a normal distribution has an equivalent z-score of roughly z = 1.282. The minimum time spent watching TV, X, at the 90th percentile is:

$z=\frac{X-\mu}{\sigma} \\1.282=\frac{X-2.8}{1.5}\\ X=4.72\ hours/day$

On a typical day, you must watch at least 4.72 hours of TV to be in the upper 10%.

Marizza181 [45]

For a 7 sides polygon which is called heptagon or septagon
Interior angles = (7-2)*180/7 = 128.57°
Exterior angle = 180 - 128.57 = 51.43°
Central angle = 360/7 = 51.43°

The statements which are correct:

3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle

5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57°

7. The central angle ABCDEFG is the same measure of the exterior angle
