The radius of a sphere whose surface area is 324*pi cm² is:
R = 9 cm.
What is the radius of the sphere in the image?We know that the surface of a sphere of radius R is given by:
S = 4*pi*R^2
Where pi = 3.14
Here we know that a sphere has a surface of 324*pi cm², then we can write the equation:
S = 324*pi cm² = 4*pi*R^2
We can divide both sides by pi, so we get:
324 cm^2 = 4*R^2
Now we can solve that equation for R, we will get:
R^2= (324 cm^2)/4 = 81cm^2
R = √(81 cm^2)
R = 9cm
The radius of the sphere is 9cm.

Solve for indicated value
Solved equation is, x = 4/3 + 2y/3
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
here we have,
Write equation
6x - 4y = 8
Then,
Solve for x
Add 4y to both sides: 6x = 8 + 4y
Divide both sides by 6: x = 8/6 + 4y/6

Step-by-step explanation:
if a+b+c=9 and ab+bc+ca-26 find a²+b²+c²?
Answer:
we have :
(a+b+c)² = a² + b² + c² + 2(ab+bc+ca)
a+b+c= 9
and
ab+bc+ca = 26
Substituting the values in the above formula,
We get,
9² = a² + b² + c² + 2×26
81 = (a² +b² +c²) + 52
(a² +b²+c²) = 81-52
(a²+ b² + c²) = 29 is a required answer.

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 10) = 10. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 10 = 100. In the following intermediate step, cancel by a common factor of 2 gives 3/5. In other words - nine tenths minus three tenths is three fifths.

c) The height of each cylinder in a set of food-storage containers is 30 cm.
The radius of the largest container is 10 cm.
The volume of the smallest container is one-third the volume of the largest container.
The volume of the middle-sized container is two-thirds the volume of the largest
container. What is the volume of each container?
Answer:
Volume of smallest container = 3141.6 cm³
Volume of middle sized container = 6283.2 cm³
Volume of largest container = 9424.8 cm³
Step-by-step explanation:
The formula to find the volume of a cylinder = πr²h
The height of each cylinder in a set of food-storage containers is 30 cm.
The radius of the largest container is 10 cm.
Step 1
We can find the volume of the largest cylinder
= r = 10cm
h = 30cm
Volume of largest cylinder = π × 10² × 30
= 9424.8 cm³
Step 2
We find the volume of the smallest container
We are told in the question:
The volume of the smallest container is one-third the volume of the largest container.
Hence
Volume of Smallest container = 1/3 (9424.8 cm³)
= 3141.6 cm³
Step 3
The volume of the middle-sized container is two-thirds the volume of the largest container.
Hence,
Volume of the middle sized container =
2/3 (9424.8 cm³)
= 6283.2 cm³
Therefore, the volume of each container is
Volume of smallest container = 3141.6 cm³
Volume of middle sized container = 6283.2 cm³
Volume of largest container = 9424.8 cm³

Step-by-step explanation:
First, find the GCF of 6 and 27, which is 3.
Factors of 6: 1, 2, 3, 6
Factors of 27: 1, 3, 9, 27
Then, find the greatest value of the variable d^3 and d^2, which is d^2. Since this is a variable, we just need to take out the highest degree accompanying the variable.
27(d^2)
6d(d^2)
Combine both of your findings to get 3d^2.
