What is the surface area of a sphere with a radius of 14 units?

Answers

Answer 1

Answer:

Answer:

SA =784 pi units ^2

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

The radius is 14

SA = 4 pi (14)^2

SA =784 pi units ^2

Answer 2

Answer:

Answer:

Surface area= 784π units²

Step-by-step explanation:

Surface area= 4×π×r²

Surface area= 4×π×(16)²

Surface area= 4×(16)²×π

Surface area= 784π units ²

Larisa buys 5 hats for $9.99 each. how much does she spend

Answers

If you would like to know how much money does Larisa spend on the hats, you can calculate this using the following steps:

5 hats * $9.99 = 5 * 9.99 = $49.95

The correct result would be $49.95.

5 × $9.99 = $49.95 spent Larisa.

The solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?A. 0.8 = 0.8
B. –0.8 = –0.8
C. 3 = 3
D. –3 = –3

Answers

we have

$1.4n + 2 = 2n + 3.2$

we know that

If $n=-2$ is a solution of the equation

then

the value of n must satisfied the equation

Substitute the value of n in the equation

$1.4*(-2) + 2 = 2*(-2) + 3.2$

$-2.8 + 2 = -4 + 3.2$

$-0.8 = -0.8$ ----> the equation is true

The value of n is a solution of the equation

therefore

the answer is the option B

$-0.8 = -0.8$

1.4(-2)+2=2(-2)+3.2
-0.8=-0.8

Answer:

Below;)

Step-by-step explanation:

We know force = mass * acceleration

So Given, mass = 0.6 mg

We know 1mg = 10^-3 g
and 1g = 1/1000 kg
So 1mg = 10^-6 kg

Hence, Mass: 0.6 mg = 10^-6 * 0.6 kg

Also Acceleration = 7.5 km/s²

We know 1km = 1000 m

Acceleration = 7.5*1000 m/s²
Acc = 7500 m/s²

Putting values, we get Force as:

F = ma
F = 0.6*10^-6 kg* 7500 m/s²
F = 4500 * 10^-6 N
F = 4.5 * 10^-3 N

pen has 1/2 cup and 1/8 cup measuring cups. What are two ways he could measure out 1 3/4 cups of flour.

Answers

There are numerous ways he could do this, but for example, let's take two ways which are common:

1) He could take the 1/2 cup twice which equals 1, and then he could measure 6 of 1/8 cups which would be 6/8 or 3/4.

2) Way number two could be if he took the 1/2 four times, which would give him 2, and then he could remove 2 1/8 cups out of the 2 which would give him 1 3/4.

Polynomials
(14x3y2z)4

Answers

With the problem in figures, solving the given polynomials would be based on how it is being situated. If 3,2 and 4 are exponents, you are going to distribute the 3rd exponent which is 4 to the rest of the numbers so the figure goes 14 to the power of 4 then x to the power of 3 multiplied by 4 and y to the power of 2 multiplied by 4. With its polynomial term, the simplified term is 38416 x to the power of 12 y to the power of 8 and z to the power of 4

Final answer:

The result of raising the polynomial (14x3y2z) to the 4th power is 38416x12y8z4. This is calculated by individually multiplying each part of the polynomial by itself 4 times.

Explanation:

The problem is asking you to calculate the result of raising a polynomial (14x3y2z) to the 4th power.

The operation refers to using the rule of powers which states that any base with an exponent is multiplied by itself the amount of times indicated by the exponent. The result should therefore be calculated as follows:

(14x3y2z)4 = 38416x12y8z4

To find the answer, we raised each part of the polynomial to the 4th power. 144 equals 38416, (x3)4 results in x12 because you multiply the exponents, (y2)4 results in y8 for the same reason and z4 because anything to the power of 4 is itself raised 4 times.
