a. what is 4PI 16?

b. what is 4/3 PI 4^3 Put this in your google search window
4/3 * PI* 4^3 =

whats the answer? 3k ppl viewed ts and no answer

My apologies for the delay in response. The answer to the second question is 268 m3.

Ah, the surface area of a sphere! It's like trying to wrap a present without any corners to fold! Now, let's dive into some mathsy fun. The formula to find the surface area of a sphere is 4πr², where r is the radius. So, with a radius of 4 meters, we have:

Surface Area = 4π(4)²
Surface Area = 4π(16)
Surface Area ≈ 201 m²

So, the surface area of the sphere, rounded to the nearest square meter, is 201 m². Ta-da! Now, let's move on to the volume, shall we?

To find the surface area of a sphere, you can use the formula A = 4πr^2, where A represents the surface area and r represents the radius of the sphere.

In this case, the radius of the sphere is given as 4 meters. Plugging this value into the formula, we have A = 4π(4^2).

Simplifying further, we have A = 4π(16) = 64π.

To round this value to the nearest square meter, we need to find the approximate value of 64π in square meters.

Taking π as approximately 3.14, multiply it by 64 to get approximately 201.

Therefore, the surface area of the sphere, rounded to the nearest square meter, is 201 m².

Now let's move on to finding the volume of the same sphere.

The volume of a sphere can be found using the formula V = (4/3)πr^3, where V represents the volume.

Again, the radius of the sphere is given as 4 meters. Plugging this value into the formula, we have V = (4/3)π(4^3).

Simplifying further, we have V = (4/3)π(64) = (256/3)π.

To round this value to the nearest square meter, we need to find the approximate value of (256/3)π in cubic meters.

Taking π as approximately 3.14, multiply it by (256/3) to get approximately 268.

Therefore, the volume of the sphere, rounded to the nearest square meter, is 268 m³.
