Find the height of a cone with a diamater of 12m whose value is 151 meters cubed, then round it to the nearest meter
Mariana [72]

Answer:

Height= 4m (nearest meter)

Step-by-step explanation:

\boxed{volume \: of \: cone =  \frac{1}{3} \pi {r}^{2}h }

Diameter= 2(radius)

Given that the diameter is 12m,

radius of cone

= 12 ÷2

= 6m

Let the height of the cone be h meters.

151 =  \frac{1}{3} \pi(6^{2} )(h)

151 = 12\pi h

h =  \frac{151}{12\pi}

h= 4.0054 (5 s.f.)

Thus, the height of the cone is 4m. (nearest meter)

Question 10(Multiple Choice Worth 1 points)
dezoksy [38]

Step-by-step explanation:

Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.

We sort the same data collected in increasing order:

{0, 1, 2, 4, 4, 5, 5, 24}

There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.

Since they are equal, the Median is 4.

Our answer is Median; 4.

The exact radius of a circle with a circumference 36 meters.
Lelechka [254]
Circumference = pi x diameter
So for this it is
36 = 3.14 x d (d = r x 2)
36 / 3.14 = 2r
11.46 = 2r
11.46 / 2 = r
5.73 = r
