Answer:890.12 cm^3
Step-by-step explanation:
The formula for the volume of a cylinder is

V=628.3185307 cm^3
or simply
V=628.32 cm^3
Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.
Next, the formula for the volume of a sphere is

so the volume of a hemisphere is half of that or:

V= 261.7993878 cm^3
or simply
V=261.80 cm^3
Finally, you add both of the volumes together to get
V= 890.1179185 cm^3
or simply
V=890.12 cm^3
Answer:
8.5
Step-by-step explanation:
First you have to turn 8/10 and 1/3 into equivalent fractions. 8/10 turns into 24/30 and 1/3 turns into 10/30. 24/30 minus 10/30 equals 14/30. After u simplify 14/30 you get 7/15.
Your answer is 7/15
The area is 57 square feet.
Small rectangle is 4 x 3 which is 12.
Big rectangle is 7.5 x 6 which is 45.
Add both areas of the shapes and you get 57.
