Your answer is 78.
Area of a triangle: 1/2 base * height
Area of a rectangle: length x width
Calculate the area of all the faces separately and add them up to solve.
Answer:
The nearest degree of the angle between the 8cm and 9cm sides is:
Step-by-step explanation:
To obtain the correct angle in a small triangle like the triangle formed with the measures in the exercise is a little bit hard, in a change of this, I used a triangle calculator, with this I obtained the right angle formed by the sides with 8 cm and 9 cm, which I'm gonna add like an attachment.
From this image, you can guide yourself to draw the triangle without mistakes and to identify the right angle, which is 40,8° but the compass is not so defined, by this reason you can take it like 41° or 40°.
You just divide 72 to 32
8x4=32
72/32=2.25
Answer is 2.25$ per slice
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.
6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
