Answer:
1256000
Step-by-step explanation:
My example:
Find the radius of the sphere by substituting 4.5? ft^3 for V in the formula in Step 1 to get: V=4.5? cubic feet.= (4/3)?(r^3)
Multiply each side of the equation by 3 and the equation becomes: 13.5 ? cubic feet =4?(r^3)
Divide both sides of the equation by 4? in Step 4 to solve for the radius of the sphere. To get: (13.5? cubic feet)/(4?) =(4? )(r^3)/ (4?), which then becomes: 3.38 cubic feet= (r^3)
Use the calculator to find the cubic root of 3.38 and subsequently the value of the radius “r” in feet. Find the function key designated for cubic roots, press this key and then enter the value 3.38. You find that the radius is 1.50 ft. You can also use an online calculator for this calculation (see the Resources).
Substitute 1.50 ft. in the formula for SA= 4?(r^2) found in Step 1. To find: SA = 4?(1.50^2) = 4?(1.50X1.50) is equal to 9? square ft.
Substituting the value for pi= ?= 3.14 in the answer 9? square ft., you find that the surface area is 28.26 square ft. To solve these types of problems, you need to know the formulas for both surface area and volume.
Answer
Q
Step-by-step explanation:
Because the Q is on top of the 5 It is the absolute value
Answer: 84
Step-by-step explanation:
4 x 21 is 84 a fraction can be simplified and be a whole number so if 84 divided by 4 it will be 21 if you want to write it as a fraction it will be 21/1 which is equal to 21

Answer: Cluster Sampling
Step-by-step explanation: Sampling is the process of collecting a representative of a particular Population of persons, activities, materials etc in order to use them for an experiment or research. Sampling can be done in different ways which include Cluster Sampling, random Sampling, stratified Sampling etc.
The activities of the Pollster using a random number to choose the residents of a given location is a Sampling method by Clustering.
Cluster Sampling is the process of identifying the cluster of participants representing the population and their inclusion in the sample group.
