I see it’s asking you how you can find the volume of a hemisphere on question 1. Which would be V = (2/3)πr.
The volume of a hemisphere = (2/3)πr3 cubic units. Where π is a constant whose value is equal to 3.14 approximately. “r” is the radius of the hemisphere. volume of a cone is 1 3 π r 2 h \frac { 1 } { 3 } \pi r ^{ 2 } h 31πr2h, where r denotes the radius of the base of the cone, and h denotes the height of the cone. formula to find the volume of a hemisphere is 2TTr3 / 3, where pi is 3.14, and the radius is half of the diameter.
Since you have a width of 30 ft, I’m guessing 30 x 10 divided by half of 3.14. I hope this helped ! Please leave a brainliest mark and a thanks (:

Answer:

Step-by-step explanation:

Step 1: 6(x^2-1) [(6x-1)/(6(x+1)]

Step 2: [6(X+1) (X-1) (6X-1)] / 6(X+1)

Explanation: Factor out the (x^2-1)

Step 3: (6X-1) (X-1)

Explanation: Cancel out common terms on the top and the bottom of the fraction.

Step 4: 6X^2 - 6X-X+1

Explanation: Multiply out and Simplify

xz_007 [3.2K]

Answer:

x = 20

Step-by-step explanation:

If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

$\rm \longrightarrow \angle 2 = \angle 5 \\ \\ \rm \longrightarrow 3x - 20 = x + 20 \\ \\ \rm Add \ 20 \ both \ sides: \\ \rm \longrightarrow 3x - 20 + 20 = x + 20 + 20 \\ \\ \rm \longrightarrow 3x = x + 40 \\ \\ \rm Substrate \ x \ from \ both \ sides: \\ \rm \longrightarrow 3x - x = x - x + 40 \\ \\ \rm \longrightarrow 2x = 40 \\ \\ \rm Divide \ both \ sides \ by \ 2: \\ \rm \longrightarrow \frac{ \cancel{2}x }{ \cancel{2}} = \dfrac{40}{2} \\ \\ \rm \longrightarrow x = 20$

What is -3 < p/2 < 0

AveGali [126]

Answer:

$-6 \le p < 0$

In interval notation, the solution is [-6, 0).

Step-by-step explanation:

$-3 \le \dfrac{p}{2} < 0$

Multiply the three sides by 2.

$-3 \times 2 \le \dfrac{p}{2} \times 2 < 0 \times 2$

$-6 \le p < 0$

In interval notation, the solution is [-6, 0).

Write the place value of the underlined digit and round each number to the place of the underlined digit plus name the place val

mylen [45]

Each number after the decimal goes in this order:
tenth
hundredth
thousandth
1. Looks like it's under the second number after the decimal. This would be the hundredth. The number after it is less than 5 so you would round down and keep the number 7, which makes 0.67
2. Being under the first number after the decimal, it would be the tenth. The number 8 is higher than 5 so you need to round the 2 up to three, making it 4.3
Do you think you could solve the rest or would you like more examples?
