Circumference = 2*pi*radius

If the circumference is 7,850, we can create the following equation.

7,850 = 2*pi*radius

Divide both sides by 2pi

7,850 / 2pi = radius = <span>1249.36 units</span>

Hello!

First of all we need to find the diameter. To do so we divide the circumference by pi.

7,850/3.14=2500

Since the radius is half the diameter, we just divide this number by 2.

2500/2=1250

The radius of this circle is 1250 unites.

I hope this helps!

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet. Find the measure of ∠V to the nearest tenth of a degree.
Crazy boy [7]

Answer:

m<V = 11.2 degrees

Step-by-step explanation:

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet.

From the triangle;

UV = hypotenuse = 6.2feet

WU = opposite = 1.2feet

Required

m<V

Using the SOH CAH TOA identity

sin m<V = opp/hyp

sin m<V = WU/UV

sin m<V = 1.2/6.2

sin m<V = 0.1936

m<V = arcsin(0.1936)

m<V = 11.16

m<V = 11.2 degrees ((to the nearest tenth of a degree)

PLS HELP SOON!! -Sweet tooth confectioners are going to mark their 50th anniversary by producing a limited edition chocolate bar
marshall27 [118]

The volume of the rectangular chocolate bar is 130 cm³.

<h3 /><h3>How to find the volume of rectangular prism?</h3>

volume of the rectangular chocolate prism = lwh

where

  • l = length
  • w = width
  • h = height

Therefore,

l = 0.65 m = 65 cm

h = 2 cm

w = 1 cm

Hence,

volume = 65 × 2 × 1

volume of the chocolate bar = 130 cm³
