The surface area of a sphere is 314.16 square units.
What is a sphere?A sphere is a 3 dimensional figure, which is made up of all points in the space, which lie at a constant distance called the radius, from a fixed point called the center of the sphere.
For the given situation,
The radius of the sphere,r = 5 units
The formula of the surface area of a sphere is
[tex]A=4\pi r^{2}[/tex]
On substituting the above values,
⇒ [tex]A=4(3.14)(5)^{2}[/tex] [∵ π = 3.14]
⇒ [tex]A=(4)(3.14)(25)[/tex]
⇒ [tex]A=314.16[/tex]
Hence we can conclude that the surface area of a sphere is 314.16 square units.

1. Cadence has a collection of 52 dolls that all have either blue-eyes or green-eyes.
Cadence has 16 more blue-eyed dolls than green-eyed dolls. How many green-eyed dolls
does Cadence have?
Answer:
Cadence has 18 more green eyed dolls
Step-by-step explanation:
1. 52-16=36
2. 36÷2=18
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Rhythm has an assortment of 52 dolls that all have either blue-eyes or green-eyes. Rhythm has 16 additional blue-looked-at dolls than green-peered dolls.
Let 'x' be the number of blue-eyes dolls and 'y' be the number of green-eyes dolls. Then the equations are given as,
x + y = 52 ...1
x = y + 16 ...2
From equations 1 and 2, then we have
y + 16 + y = 52
2y = 52 - 16
y = 36 / 2
y = 18
The value of x is given as,
x = 18 + 16
x = 34
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.

A firm tested the durability of four different types of tires by having 4 Cadillacs each randomly equipped with one of the types of tires. In similar fashion, 4 Fords were used, each randomly equipped with one of the tire types. In a like manner, 4 Volkswagens were each randomly outfitted with one of the four tire brands. Then each of the twelve cars ran over a test track until the tires showed signs of serious wear. At that point the average mileage of the three cars using one type of tire was compared to the average mileage of the three cars using the second type of tires, and so on. This design is:
Answer:
Randomized block design
Step-by-step explanation:
In the scenario described above, the subjects which are the different car types are grouped into fixed units of 4 called blocks with each unit then assigned randomly to a particular treatment condition, which are the 4 different types of tire. In the end, the mean mileage for each block is taken and compared to that of the other blocks. This type of research design improves the reliability of the result obtained as it also eliminates the occurrence of systematic error in the course of our experiment.
The formula V=arh gives the volume of a cylinder with radius r and height h. Find the volume of a cylinder with radius (x + 4) cm and height 5 cm. Write your answer in standard form.
Answer:
V = a (x + 4)*5 but see below.
Step-by-step explanation:
You're not going to get any kind of answer that gives V = 122 or some other pure number.
Formula
V = arh
Givens
a = pi * r
r = (x + 4)
h = 5cm
Solution
V = a * (x + 4)*5
or
V = pi * (x + 4)^2 * 5

what fraction is equivalent to 5/6 and has a numerator that is 2 less than its denominator
Answer:
Step-by-step explanation:
let the fraction be x denominator and x-2 be its numerator
according to question
5/6=x-2/x
do cross multiplication
6(x-2)=5x
6x-12=5x
6x-5x=12
x=12
therefore the fraction is
x-2/x

The Sugar Company will choose from two companies to transport its sugar to market. The first company charges $5995 to rent trucks plus an additional fee of $175.50 for each ton of sugar. The second company charges $6500 to rent trucks plus an additional fee of $150.25 for each ton of sugar.
I think we're missing part of your question. The expression for cost for the first company will be:
5995 + 175.5x, where x is the number of tons of sugar
and the expression for the cost for the second company is:
6500 + 150.25x

Answer:
Use this to get the area of any circle A = π r²
Step-by-step explanation:
I guess the upper circle has a radio of 10.5 m, then you multiply it by itself and you get that 10.5^2=110.25, and to that you add "π", and the area would be this "110.25π m."
And the other one is 7^2π=49π
