Answer:

16.3 feet

Step-by-step explanation:

find the value of the missing side using the pythagorean theorem -

a^{2} + b^{2} = c^{2}  ->  3^{2} +a^{2} =7^{2}  ->  9 + a^{2} = 49  ->  a^{2} = 40  -> take the square root of both sides: \sqrt{a} = \sqrt{40}  ->  a = 6.3

then you add it with the other two sides to get the perimeter: 6.3 + 3 + 7 = 16.3

A mysterious orb is in the shape of a sphere with radius 9.5 inches. Find the volume and surface
Andru [333]

A 9.5-inch-diameter spherical in the shape of a strange orb is present. 3591.36 m3 of volume and surface

<h3>Explain about the Radius?</h3>

The radius of a circle is the separation between any two points on its circumference. R or r is typically used to indicate it.

The diameter of a circle cuts through the centre whereas the radius extends from the centre to the edges of the circle. The diameter of a circle effectively divides the shape in two.

A circle's area is equal to pi times the radius squared (A = r2). Discover how to apply this formula to determine a circle's area given its diameter.

The radius of a circle is the distance from the center to any point on the edge. The radius is equal to the diameter in half, or 2r=d2 r=d.

  V=4 \3πr³

    = 4/3 π 9.5³

    =3591.36

Correct answers only please!
MrRissso [65]

Answer:

23.6°

Step-by-step explanation:

In this question we have to use some trigonometry to work out angle XVW. Since we are working out angles all of the trigonometric functions will have to be to the ⁻¹. The first thing we need to identify is will formula will we use out of the following:

Sin⁻¹ = Opposite ÷ Hypotenuse

Tan⁻¹ = Opposite ÷ Adjacent

Cos⁻¹ = Adjacent ÷ Hypotenuse

-------------------------------------------------------------------------------------------------------

10 = Hypotenuse

4 = Opposite

-------------------------------------------------------------------------------------------------------

We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.

Now we substitute in the values to find the value of angle XVW

Sin⁻¹ = Opposite ÷ Hypotenuse

Sin⁻¹ = 4 ÷ 10

The value of angle XVW is 23.57817848
