Answer:

138picm2

Step-by-step explanation:

An hemisphere is half of a sphere. This means a sphere is twice an hemisphere .

Surface area of sphere of same radius = twice surface area of hemisphere

Therefore

Surface area of sphere = 2 * 69

= 138 pi cm2

I hope this was helpful, Please mark as brainliest

Answer:

Volume of prism 1: 104 cubic inches

Surface area of prism 2: 650 square inches

Step-by-step explanation:

To find the volume of prism 1, set up a proportion using the side lengths and the volume of prism 2.

The ratio of the side lengths will be your scale factor. When finding volume using scale factor, you need to cube the scale factor. The numerator in the proportion are from prism 1 and the denominator is prism 2. Prism 1 is the numerator since it is the new image and we are solving for it's volume.

(\frac {4}{10}) ^{3}  =\frac{x}{1625} \\\\\frac{64}{1000} =\frac{x}{1625} \\\\

1000x=104000\\\frac{1000x}{1000} =\frac{104000}{1000} \\x = 104

To find the surface area of Prism 2, we are going to setup another proportion, but this time we are going to square the scale factor since we are finding area. Prism 2 will be the numerator and prism 1 will be the denominator.

(\frac{10}{4} )^2 = \frac{x}{104} \\\frac{100}{16} =\frac{x}{104} \\16x=10400\\\frac{16x}{16}=\frac{10400}{16}\\ x= 650
