Answer:

0.979%

Step-by-step explanation:

Given that:

Estimated value = 825 ;

Actual value = 817

Percentage error:

(|Estimated value - Actual value| ÷ actual value) * 100%

(|825 - 817| ÷ 817) * 100%

(8 / 817) * 100%

0.0097919 * 100%

= 0.979%

= 1% (nearest percent)

Find the volume of the sphere. express your answer in term of Pie​
IceJOKER [234]

Answer:

\large\boxed{36\pi}

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

R - radius

We have R = 3 ?. Substitute

V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3}\pi(27)=(4)\pi(9)=36\pi

If the radius is 30, then the volume is:

V=\dfrac{4}{3}\pi(30^3)=\dfrac{4}{3}\pi(27,000)=(4)\pi(9,000)=36,000\pi

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.

Therefore the volume:

V=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3,375)=(4)\pi(1,125)=4,500\pi

Please help with this question
never [62]

Answer:

2,744 feet³

Step-by-step explanation:

Volume = Length * Width* Hight

A cube has all the sides equal in measure so Length and Width and Hight are equal and are given in the picture to be 14 feet.

V = 14 *14*14 = 2,744 cubic feet
