Lianne drew a sphere with a radius of 7 in. She calculated its volume and wrote it below. Start Fraction question mark pi Over 3 End Fraction inches cubed

What value should be multiplied by Pi in the numerator to correctly show the volume of the sphere

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

p

step-by-step explanation:

answer is (b.

164 ft2)

a base  

18

b base  

7

h height  

8

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
