Volume = area of base *height
20 = pir^2 *h
20 = 3,14*4*h
h = 20/12,56 = 1,59 rounded 1,6
- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that
tan ß = h/r so tan ß = 1,6/2 = 0,8
tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees
hope helped
Answer:
ig i will
Step-by-step explanation:
Answer:
6. it is a square because all of the outer sides are equal
3. perpendicular because the slopes are reciprocals of eachother and the lines would form 90 degree angles

Answer:
<em>A = 32²cm</em>
Hope this helped!
Step-by-step explanation:
<h3>A = lw/2</h3>
<u>We know that the width is 8cm, and that the length of the rectangle and triangle combined is 14cm.</u>
<u />
How we find the length of the triangle itself is 14cm - 6cm, since 6cm is the rectangles length (which we know because it gives it to us at the top!)
14cm - 6cm = 8cm
<h3>Now we can plug into our formula and solve</h3>
A = 8(8)/2
A = 64/2
<h3><em>A = 32²cm</em></h3>
