Help with finding the volume of the cone pictured

jasenka [17]

Volume of the cone = 56.52 in³

Solution:

Diameter of the cone = 6 in

Radius of the cone = 6 ÷ 2 = 3 in

Height of the cone = 6 in

The value of π = 3.14

<u>To find the volume of the cone:</u>

Volume of the cone = $\frac{1}{3} \pi r^{2} h$

$$=\frac{1}{3} \times 3.14 \times 3^{2} \times 6$

$$=3.14 \times 18$

= 56.52

Volume of the cone = 56.52 in³

Hence the volume of the given cone is 56.52 $\text{in}^3$ .

Suppose that many large samples were taken from population A, which is normally distributed, and population c, which is not norm

OLEGan [10]

Answer:

Population A

Step-by-step explanation:

Think about. If population A already known for normally distribution AND you take large samples. The rest would still be distributed, Which keeps population A a Normal Distribution.

but Population C is nor normally distributed, so if you take away large samples. it will deteriorate its distribution so it won't get any better or in this case, normal. so. it is Population A.

The revised Daily Value for calcium is 1,300 mg per day. How many servings of this food would you have to eat to get 100% DV for

Ne4ueva [31]

Answer:

Taking into account the values showed for this food (image attached). It is required

Servings.

Step-by-step explanation:

The total calcium (Cat) required is 1300 mg/day.

One serving of this food can have 260 mg.

First step is to suppose one day of calculation. t = 1 day.

Cat = (1300 mg/day)(1 day) = 1300 mg Calcium.

One single serving can have 260 mg Calcium (Cas). So, we need to calculate the amount of servings (N) required to complete 1300 mg.

Cat = Cas*N

N = Cat/Cas = 1300 mg/260mg

N = 5.

Finally amount of servings is five N = 5.
