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

topjm [15]

sides 2 * 6 * 4 =48 and 6*4=24

bottom 6*2.5 =15

2.5*4=10

10*2=20 that's the area of 2 smaller sides

Step-by-step explanation:

we add up the dimensions together 48+20+15=83

so the final equation becomes (6*2.5)+2(2.5*4)+2*(6*4)=83
