Answer: Cylinder 1 - 25.1327412283 cubic cm
Cylinder 2 - 100.5309469149 cubic cm
Cylinder 3 - 226.1946710585 cubic cm

For each of the cylinders, we will need to use the same formula, h(pi(r squared)).

Cylinder 1 - 8(pi(1 squared)). 1 squared = 1. pi × 1 = 3.1415926536. 3.1415926536 × 8 = 25.1327412283 cubic cm.

Cylinder 2 - 8(pi(2 squared)). 2 squared = 4. 4 × pi = 12.5663706144. 12.5663706144 × 8 = 100.5309469149 cubic cm.

Cylinder 3 - 8(pi(3 squared)). 3 squared = 9. 9 × pi = 28.2743338823. 28.2743338823 × 8 = 226.1946710585 cubic cm.

- Hope it helps!

Patty made a banner that has an area of 175 square inches. The length and width of the banner are whole numbers. The length is 7
Leviafan [203]

Answer:

Length = 35

w = 5

Step-by-step explanation:

l x w = area

7y x y = 175

7y^2 = 175

y^2 = 175/7

y^2=25

y=5

The length is 7y, so it's 5 times 7 or 35.

The width is just y, so it's 5.

Which is not a correct way to rewrite this expression using the distributive
Effectus [21]

Given:

The expression is

(2x^2+4x-7)(x-2)

To find:

The expression which is not a correct way to rewrite the given expression.

Solution:

We have,

(2x^2+4x-7)(x-2)

Using distributive property, we get

=(2x^2)(x-2)+(4x)(x-2)+(-7)(x-2)

=(2x^2)(x)+(2x^2)(-2)+(4x)(x)+(4x)(-2)+(-7)(x)+(-7)(-2)

Using distributive property the given expression can rewritten as:

=(2x^2+4x-7)(x)+(2x^2+4x-7)(-2)

Only the expression in option A is not a correct way to rewrite the given expression because (2x^2+4x-7) is not distributed to (x-2) properly.

Therefore, the correct option is A.
