Answer: 1/2
Step-by-step explanation:
Circumference is equal to 2πr. Now, if the circumference itself is equal to pi, then the equation becomes the following:
π = 2πr
Divide both sides by pi:
1 = 2r
Divide both sides by 2:
r = 1/2
Step-by-step explanation:
Answer:
i think its 1
Step-by-step explanation:
Step-by-step explanation:
the volume of a cylinder is as for any regular shaped object
ground area × height
here the ground area is a circle, so we get
pi×r²×h
with r being the radius (half the diameter), and h the height.
therefore,
pi×(2.7/2)²×10 = 3.14×1.8225×10 = 57.25552611... cm³
so, the first option is correct.
Answer: (x^2+1) • (x^2-10)
Step-by-step explanation:
1. Write “-9x^2” as a difference
X^2-10x^2
2. Factor out x^2
X^2 (x^2+1)
3. Factor out -10
-10(x^2+1)
4. Factor out x^2+1 to get:
(X^2+1) (x^2-10)
