{\pink{\underline{\textsf{\textbf{Answer : }}}}}

➡️ 37,680m² will be the curved surface area of the cylindrical tank.

{\purple{\underline{\textsf{\textbf{Explanation : }}}}}

Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm

We need to find the curved surface area

<u>We know that</u>,

➩ Curves surface area of a cylinder = 2πrh

r (radius) = 30cm.

h (height) = 200cm.

Therefore,

➩ Curves surface area of a cylinder:

➩ 2 × 3.14 × 30 × 200

➩ 2 × 18,840

➩ 37,680 m² ans.

Which arrangement shows 318 , 3.7, 334 , and 3.89 in order from least to greatest?
Stolb23 [73]

Answer: OPTION D.

Step-by-step explanation:

<h3> The complete exercise is: "Which arrangement shows 3\frac{1}{8}, 3.7, 3\frac{3}{4}, and 3.89 in order from least to greatest?"</h3><h3> </h3>

Convert from mixed numbers to decimal numbers.

The steps to do this, are the following:

1. You must divide the numerator of the fraction by the denominator.

2. Then you must add the quotient obtained to the whole number part.

Applying this procedure, you get that:

3\frac{1}{8}=3+0.125=3.125

3\frac{3}{4}=3+0.75=3.75

Now that you have all the numbers in decimal form, you can order from least to greatest:

3.125,\ 3.7,\ 3.75,\ 3,89

Therefore, you can conclude that the correct arrangement is:

3\frac{1}{8},\ 3.7,\ 3\frac{3}{4},\ 3,89

Show any calculations, including 180 degrees, go step by step pls.​
ICE Princess25 [194]

Answer:

<em>120°, 120°, 60°, 60°</em>

Step-by-step explanation:

m∠1 = 180° - 60° = 120°

m∠1 = m ∠2 (alternate interior)

m∠3 = 60° (vertical to given angle)

m∠4 = m∠3 (alternate exterior)

If f(x) = -7x + 1 and g(x) = Square root of x-5,<br> what is (fºg)(41)?
Ghella [55]

This is similar to the other question you posted. Follow the same steps as before.

First find g(41).

g(41) = sqrt{x - 5}

g(41) = sqrt{41 - 5}

g(41) = sqrt{36}

g(41) = 6

We now find f(6).

f(6) = -7(6) + 1

f(6) = -42 + 1

f(6) = -41

Answer:

(fºg)(41) = -41

Did you follow?
