Find the area of an equilateral triangle with radius 3 root 3.leave in simpliest radical form

Mathematics
1 answer:
goldenfox [79]4 years ago
8 0

Answer:

Area = 27√3/4 square units

Step-by-step explanation:

Since the shape is an equilateral triangle, all the sides will be equal

Area of the triangle = 1/2 * base * height

Get the height

(3√3)² = h²+(3√3/2)²

27 = h² + (27/4)

h²= 27 - 27/4

h² = 27 - 6.75

h² = 20.25

h = √2025/100

h = 45/10

Area = 1/2 * 3√3 * 45/10

Area = 135√3/20

Area = 27√3/4 square units

Answer:

     207.24 in²

Step-by-step explanation:

The "r" in the formula stands for the radius of the cylinder. That is half the diameter, so is 3 in. The "h" in the formula stands for the cylinder height, shown as 8 in. Put these values in the formula and do the arithmetic.

  SA = 2πr(r +h) = 2(3.14)(3 in)(3 in + 8 in) = 6.28(33 in²)

  SA = 207.24 in²

You have 275 square inches of wrapping paper. Do you have enough wrapping paper to wrap the gift box shown?
Zigmanuir [339]

The surface area of the box is bigger than the <em>surface area</em> of the available wrapping paper. <em>Thus, you don't have enough wrapping paper to wrap the gift box.</em>

The given parameters;

  • area of the wrapping paper available, A = 275 square inches
  • volume of the gift box, V = 343 in²

First, determine the length of each side of the box;

The length of each side is represented with x;

x³ = 343

x = \sqrt[3]{343} \\\\x = 7 \ inches

Second, find the surface area of the box;

surface area of the box, A = 6x²

A = 6(7)²

A = 294 in²

The surface area of the box is bigger than the <em>surface area</em> of the available wrapping paper. Thus, you don't have enough wrapping paper to wrap the gift box.
