What's the question or what you are trying to find
A40=a1 +(40-1)r
in this case r is 3 beceause -2+3 will be 1 etc
a40=-2 +39*3
Answer:
(-3,3) Hope that this does help!
If we have 156 beads and we can make one bracelet with 9 beads we divide 156 by 9 and get 17 1/3. since we cannot have 1/3 of a bracelet, we can make 17 bracelets.
Formula for a sphere is V = (4 ⁄ 3) π r^3
The picture shown showed the diameter.
Half of a diameter is the radius.
The radius is 2.95 yd.
Let’s plug in the values into the formula.
V = (4/3) 3.14 (2.95)^3
V = 107.48
NOW THATS THE ANSWER FOR A WHOLE SPHERE BUT YOURE LOOKING FOR THE HEMISPHERE.
So let’s divide that in half:
107.48/2 = 53.74
Your answer is B.) 53.74 yd
