85/5
(50+35)/5
50/5 + 35/5
10+7=17
Answer:
The value of x is 9.
Step-by-step explanation:
55°
(3 x + 23)
75°
The sum of all the angles of triangle is 180°.
55 + 3 x + 23 + 75 = 180
3 x = 27
x = 9
So, the value of x is 9.
D is the answer for ur question
Start with the formula of the volume of a cone
volume of cone = (1/3) pi * r^2 * h
Now you double the radius and the height.
The radius becomes 2r, and the height becomes 2h.
volume of cone = (1/3) pi * (2r)^2 * 2h
= (1/3) pi * 4r^2 * 2h
= (1/3) pi * 8r^2 * h
= 8 * (1/3) pi r^2 * h
As you can see, the volume became 8 times larger.
8 * 350 cm^3 = 2800 cm^3
