For this you need to use the reverse cosine function
Cos^-1 (.25)
75.6
Okay so multiply everything by 2 6yrds×2=12yrds. 9ft×2=18ft. 4in×2=8in. So the answer is: 12yrds 18ft 8in
Answer:
- HOW TO FIND VOLUME OF PRISM -
1st step - Write the formula for finding the volume of a regular pentagonal prism. The formula is V = [1/2 x 5 x side x apothem] x height of the prism.
2nd step - Find the area of the pentagonal base face. Let's say the length of a side is 6 cm and the length of the apothem is 7 cm.
3rd step - Find the height. Let's say the height of the shape is 10 cm.
4th step - Multiply the area of the pentagonal base face times the height. ...
and last step - State your answer in cubic units.
