Answer:

The height of right circular cone is h = 15.416 cm

Step-by-step explanation:

The formula used to calculate lateral surface area of right circular cone is: $s=\pi r\sqrt{r^2+h^2}$

where r is radius and h is height.

We are given:

Lateral surface area s = 236.64 cm²

Radius r = 4.75 cm

We need to find height of right circular cone.

Putting values in the formula and finding height:

$s=\pi r\sqrt{r^2+h^2}\\236.64=3.14(4.75)\sqrt{(3.75)^2+h^2} \\236.64=14.915\sqrt{(3.75)^2+h^2} \\\frac{236.64}{14.915}=\sqrt{14.0625+h^2} \\15.866=\sqrt{14.0625+h^2} \\Switching\:sides\:\\\sqrt{14.0625+h^2} =15.866\\Taking\:square\:on\:both\:sides\\(\sqrt{14.0625+h^2})^2 =(15.866)^2\\14.0625+h^2=251.729\\h^2=251.729-14.0625\\h^2=237.6665\\Taking\:square\:root\:on\:both\:sides\\\sqrt{h^2}=\sqrt{237.6665} \\h=15.416$

So, the height of right circular cone is h = 15.416 cm

Evaluate 2/4 _ 8z + 2 (z - 5)

SIZIF [17.4K]

Let's see....

Let's first simplify step-by-step.

2/4 - 8z + 2(2-5)

= 1/2 + - 8z + -6

Combine Like Terms:

= 1/2 + -6

= (- 8z) + (1/2 + -6)

=(- 8z) + (1/2 + -6)

= - 8z + -11/2
___________________________________

Our answer:

= - 8z + -11/2

Hope This Helps!!!!!!!!

An isosceles triangle has slant height s and angle t opposite the base. Find a formula for the base length b in terms of the ang

Mars2501 [29]

OK, let's try with no figure. We have an isosceles triangle sides s,s, and b.

Opposite b is angle t.

Draw the altitude h to bisect t. We have two right triangles, legs b/2 and h, hypotenuse s. The angle opposite b/2 is t/2 so

sin(t/2) = (b/2)/s = b/2s

So we arrived at the first part,

b = 2s sin(t/2)

The area of a triangle with sides s,s and included angle t is

A = (1/2) s² sin t
