Answer:
The correct answer is 8cm.
Step-by-step explanation:
Vol. Of cone= 1/3pi r²h
= 1/3×3.14× 8²×15
= 8×8×5×3.14
64× 5×3.14
= 320×314/100
=16×314=5024 cm³
Hope this helps:) Goodluck!
13m-22=9m-6
13m-9m-22=-6
4m-22=-6
4m=-6+22
4m=16
m=16/4
m=4
<em>Therefore, m is 4</em>
david's procedure is correct becsuse Keisha didnt put the correct value of sin theta in equation, she forgot to mention negative sign. though solution are same but in other case it could have gone wrong
Answer:
20
Step-by-step explanation:
The distance between two points is found by
d = sqrt( ( x2-x1)^2+(y2-y1)^2
= sqrt( ( 10- -6)^2 + (-4 -8)^2 )
= sqrt( (16^2 + (-12 )^2)
= sqrt(256+144)
= sqrt(400)
= 20
Answer: -15/8
Step-by-step explanation:
Using PEMDAS:
[18-(-8)^2] + 16 / 2^4
(18-64)+16 / 16
-46+16 / 16
-30/16
(Simplified) -15/8
