Answer:

x = 6, <em><u>PLEASE MARK AS BRAINLIEST</u></em>

Step-by-step explanation:

<em>Let this number be x: </em>

<em>1) Increase x by 30 = x + 30</em>

<em>2) Divide the result by 2 = </em>\frac{x+30}{2}<em></em>

<em>3) The number obtained is 3 times the original number = </em>

<em></em>\frac{x + 30}{2}  = 3x<em></em>

<em></em>{x + 30} = 6x<em></em>

<em></em>30 = 5x<em></em>

<em></em>x = \frac{30}{5}<em></em>

<em></em>x = 6<em></em>

Find the volume and surface area of a sphere with radius 1 yards. Round your answer to two decimal places.
olga55 [171]

Answer:

Volume of the sphere up to two decimal places= 4.19 cubic yards

Surface area of the sphere up to two decimal places  =12.56 square yards

Step-by-step explanation:

Given:

The radius of the sphere= 1 yard

Volume of a Sphere:

                        \frac{4}{3}* \pi *r^3                                                         :\pi =\frac{22}{7} =3.14

               =\frac{4}{3}*3.14*1*1*1

               =4.187 cubic yards

Volume of the sphere up to two decimal places= 4.19 cubic yards

Surface area of the sphere= 4*\pi* r^2

                                           =4*3.14*1*1

Surface area of the sphere up to two decimal places  =12.56 square yards
