<h2><u>Answer</u>:-</h2><h3>Given:-</h3>
Radius (r) of the cylinder = 10 ft.
Height (h) of the cylinder = 6 ft.
<h3>To Find:-</h3>The lateral surface area of the cylinder.
<h2>Solution:-</h2>We know,
Formula of lateral surface area of cylinder is 2πrh.
So, Lateral surface area of the cylinder = 2 × 3.14 × 10 × 6
Lateral surface area of the cylinder = 376.8 = 377 sq. ft.
<h3>The lateral surface area of the cylinder is <u>3</u><u>7</u><u>7</u><u> </u><u>sq.</u><u> </u><u>ft</u>. [Answer]</h3>Answer: H = 20
Step-by-step explanation:
To find the hypotenuse , we will use Pythagoras theorem, which states that
The square of the hypotenuse = the square of the adjacent + the square of the opposite.
Since , we are dealing with isosceles right triangle , this means that :
both the adjacent and the opposite are equal, using the formula to find the hypotenuse , let H represent the hypotenuse , then
=
+
= 400 + 400
= 800
Take the square root of both sides
H =
can be written as
x
Therefore :
H = x
H = 20x
H = 20

Answer:
Step-by-step explanation:
This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):
On the left, the inverse sin "undoes" or cancels the sin, leaving us with
2x + 30 = sin⁻¹(1)
The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:
2x + 30 = 90 and
2x = 60 so
x = 30
You're welcome!
