The volume of a cylinder is written as V = πr²h. The volume is 324π cm³ and the height is 9 cm. Evaluating it, we will arrive at the value of radius as 6 cm. Area of the base can be obtained using the formula A = πr². If r = 6cm, area of the base will be 36π cm

I will give u the brainliest i need the answer with the steps .pls abswer soon☺☺

Answer:

ab = 24

so ac is half, so

ac = 12

and the radius is 13,

draw a line from a to o

and its tall will be 13 because it is the radius and o is the center

now use Pythagoras rule

{a}^{2}  +  {b}^{2}  =  {c}^{2}

put numbers

{12}^{2}  +  {b}^{2}  =  {13}^{2}

and solve for b

b = 5

and that is the side we want

Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales. What are Cara’s total earnin
k0ka [10]

Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is $ 4200

<h3><u>Solution:</u></h3>

Given that Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales

Let us first calculate commission earned from selling $40,000 worth of merchandise

commission earned from selling $40,000 = 6 % of $ 40,000

\text {commission earned from selling } \$ 40,000=\frac{6}{100} \times 40,000

\text {commission earned from selling } \$ 40,000=2400

Also given that Cara earns a base pay of $ 1800 per month

So Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is calculated by adding commission earned $ 2400 to base pay $ 1800 per month

<em>Cara’s total earnings in a month = base pay + commission earned</em>

Cara’s total earnings in a month = $ 1800 + $ 2400 = $ 4200

Thus the total earning of Cara in that month is $ 4200

sashaice [31]

Answer:

x=28

Step-by-step explanation:

angle b and angle c are the same measure because it is a iso triangle.

you know triangle sum is 180 so 3x+2(x+20)=180. simplify it to 5x=140

divide both sides by 5

x=28

Kazeer [188]

Answer:

Area = 1,527 in

Step-by-step explanation:

Circle area = π * r² = π * 3136 [cm²] ≈ 1527 [in²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 56 [cm] * 2 = 44.094 [inch]
