Answer:
D. a reflection over the y-axis
Answer:
+- 5 and +- 3
Step-by-step explanation:
qn 2:
4r² = 91 + 9
4r² = 100
r² = 25
r = +- 5
qn 3:
4r² = 29 + 7
4r² = 36
r² = 9
r = +- 3
Answer:
three and three eighteenths
5 3/6 = 33/6
2 1/3 = 7/3 = 14/6
33/6 - 14/6 = 19/6 = 3 1/6 or 3 3/18
Answer:
3
Step-by-step explanation:
<span>the question does not present the picture, but this
does not interfere with the resolution</span>
we know that
When a rectangle with a width of 2.5 feet and a length of 8 feet rotates it makes a cylinder with a radius r = 2.5 ft and a height h = 8 ft
volume of a cylinder=pi*r²*h-----> pi*2.5²*8----> 157 ft³
the answer is157 ft³
