Answer: The answer would be the one going a slope downwards
Step-by-step explanation:
The formula for the volume of a sphere is V=(4/3) (pi) r^3. if r is doubled then you get 2r as the radius and V=(4/3) (pi) * 8r^3 so the volume is eight times bigger than the original r value. if r is tripled the r =3r and (3r)^3 so the volume is 27 times bigger. If r is multiplied by n the radius is nr and (nr)^3 =n^3 r^3, Therefore, the volume is n^3 times bigger than the original.
Answer:
A)10.25 cm ; B)5 square cm
Step-by-step explanation:
A)
Formula:
p=(a+b+c) [p= perimeter ; a,b , and c are the side lengths.]
∴The perimeter of the triangle =(4+2.75+3.5) cm
=10.25 cm
B)
Formula:
A = 1/2 . b .h [A=area ; b= base ; h= height]
∴The area of the triangle = (1/2 . 4 . 2.5) square cm [b=4 ; h=2.5]
=5 square cm
X>7→because if x=7 the answer is 8 so it should be >7
x<-1→if 2|-1-3|=8. →-2 &-3&-4&...are smaller than -1→x<-1
The photo is an example.
Divide the diameter by 2 to get the radius.
Then times 1/3 time Pi times the radius squared times the height.
The formula is V=1/3(Pi)(radius squared)(height)
