Find the radius of a circle whose area is 576π m²
Answer:
r = 24 m
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here A = 576π , then
πr² = 576π ( divide both sides by π )
r² = 576 ( take the square root of both sides )
r = [tex]\sqrt{576}[/tex] = 24

use the geometric mean (leg) theorem. what is the value of a?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Geometric Mean (leg) theorem.
So according to the rule, we know that, here altitude = h and left side is 6 and right side is 14 , so we get as,
==> altitude/left = right/altitude
==> h/6 = 14/h
==> h^2 = 14*6
==> h^2 = 84
2.) so now we apply the Pythagoras theorem in triangle ∆DCB
so we get as,
==> (14)^2 + h^2 = a^2
==> 196 + 84 = a^2
==> 280 = a^2
==> a = √280
==> after simplified => a = √70*4
==> a = 2√70 units
hence the correct answer is a => 2√70 units.

Answer:
27.6 is the area
Step-by-step explanation:
Area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).
What is triangle?" Triangle is defined as two dimensional geometrical shape with three vertices, three sides and three angles enclosed in it."
Formula used
Pythagoras theorem
(Hypotenuse)² = (Base)² + (Height)²
Area of a right triangle = [tex]\frac{1}{2} \times b\times h[/tex]
[tex]b[/tex] represents the base of the triangle
[tex]h[/tex] represents the height of the triangle
According to the question,
In a given triangle,
Hypotenuse [tex]= 11in[/tex]
Height [tex]= 6in[/tex]
Substitute the value in Pythagoras theorem to get the measure of base,
[tex](11)^{2} = b^{2} + 6^{2}\\\\\implies b^{2}= 121 -36\\\\\implies b =\sqrt{85}[/tex]
Substitute the value in the formula to find area of a triangle,
Area of a triangle [tex]= \frac{1}{2}\times \sqrt{85} \times 6[/tex]
[tex]= \frac{1}{2} \times 9.22 \times 6\\\\= 9.22 \times 3\\\\= 27.66[/tex]
≈ [tex]27.6in^{2}[/tex] ( round to nearest tenth)
Hence, area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).

Calculate the surface area of an open cylinder measuring 35cm in diameter and 60cm high.
Answer:
6598.2 in^2
Step-by-step explanation:
Given data
Diameter= 35in
Radius= d/2= 35/2= 17.5in
Height = 60cm
The expression for the curve surface area of a cylinder is
CSA=2πrh
substitute
CSA= 2*3.142*17.5*60
CSA= 6598.2 in^2
Hence the CSA is 6598.2 in^2

Function ggg can be thought of as a scaled version of f(x)=x^2f(x)=x 2 f, left parenthesis, x, right parenthesis, equals, x, squared. A parabola labeled f represents the equation y equals x squared. A parabola labeled g passes through the point negative 4, 8, through the origin, and through the point 4, 8. Write the equation for g(x)g(x)g, left parenthesis, x, right parenthesis.
A scaled function is a dilated function
The function g(x) is: [tex]\mathbf{g(x) = \frac 12x^2}[/tex]
Function f is given as:
[tex]\mathbf{f(x) = x^2}[/tex]
Function g is a scaled version of f(x).
So, we have:
[tex]\mathbf{g(x) = kx^2}[/tex] --- where k is the scale
The graph of g(x) passes through (4,8).
So, we have:
[tex]\mathbf{8 = k \times 4^2}[/tex]
[tex]\mathbf{8 = k \times 16}[/tex]
Divide both sides by 16
[tex]\mathbf{\frac 12 = k }[/tex]
So, we have:
[tex]\mathbf{k = \frac 12 }[/tex]
Substitute [tex]\mathbf{k = \frac 12 }[/tex] in [tex]\mathbf{g(x) = kx^2}[/tex]
[tex]\mathbf{g(x) = \frac 12x^2}[/tex]
Hence, the function g(x) is: [tex]\mathbf{g(x) = \frac 12x^2}[/tex]
