Find the radius of a sphere whose surface area is 154cm².​with stepss
worty [1.4K]

Answer:

THIS IS YOUR ANSWER:

area \: of \: spere \:  = 4\pi \: r {}^{2}  \\ 154cm {}^{2} = 4 \times  \frac{22}{7}  \times r {}^{2}

\frac{154 \times 7}{4 \times 22} = r {}^{2} \\ r {}^{2} = 12.25 \\

r =  \sqrt{12.25} \\ r = 3.5cm

Simplify.<br><br> 1/cosθ + tan^2θ/cosθ<br><br> • 1 + sinθ<br> • sec^3θ<br> • 1<br> • cos^3θ
olchik [2.2K]

Answer:

I'm guessing the answer is sec³θ

Step-by-step explanation:

I tried this problem and I got 1/cos³θ and clicked cos³θ, but that answer was incorrect. In my lesson, there were the options:

1. sec³θ

2. cos³θ

3.  secθ

I didn't have options 1 + sinθ or 1 as answers. If sec³θ is not the correct answer, please correct me.

Find x<br>and<br>each of the<br>interior angles.​
Kay [80]

Answer:

Part 1) x=27

Part 2) The measure of the interior angles are 64°-67°-49°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In this problem

(3x-17)^o+(x+40)^o+(2x-5)^o=180^o

Solve for x

Combine like terms

(6x+18)^o=180^o

Subtract 18 both sides

6x=180-18

6x=162

Divide by 6 both sides

x=27

step 2

Find the measure of each interior angle

substitute the value of x in each measure

(3(27)-17)=64^o

(27+40)=67^o

(2(27)-5)=49^o
