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

Please help me with this -2 - (-0.7)
Amanda [17]

Anytime you subtract a negative number, it changes it to adding a positive number.

-2 + 0.7

Since we are adding, we will have an arrow going to the right

-2 + 0.7 = -1.3

Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3

Best of Luck!
