The area of a circle with chord length of 3√2cm is 28. 3 cm²

<h3>How to determine the area</h3>

The formula chord length of  a circle is expressed as;

Chord Length = 2 × r × sin(c/2)

Where;

  • r is the radius
  • c is the angle formed by the chord and the circumference of the circle
  • Chord length = 3√2

Let's substitute into the formula

3√2 = 2r sin 90/ 2

3√2 = 2r sin 45

3√2 = 2r × 1/ √2

2r = 3√2 ×√2/ 1

2r = 6

Make 'r' the subject

r = 6/2

r = 3cm

The formula for area of a circle is expressed as;

Area = πr²

Area = 3.142 × (3)²

Area = 3. 142 × 9

Area = 28. 3 cm²

Thus, the area of a circle with chord length of 3√2cm is 28. 3 cm²

the base of the founten is rectangular . its dimention 1 2/3 feet by 2 2/3 feet . what is the area of the base of the founten
Montano1993 [528]
The area of a rectangle is calculated by multiplying the length of the rectangle and the width of the rectangle. In this case, the length (the longer side) is 2 2/3 feet while the width (shorter side) is 1 2/3 feet. To multiply fraction, first convert mixed numbers into improper fractions:

2 2/3 = 8/3
1 2/3 = 5/3
Multiplying the two fractions yield: 
8/3 x 5/3 = 40/9 ft2 

The final answer is 40/9 ft2 or 4 4/9 ft2.

Sylvia plans to place 617 stamps in an album. Each page of the album holds 5 stamps. She uses division to find out how many full
bija089 [108]

Answer:

123 full pages

Step-by-step explanation:

Given

Total\ Stamps = 617\ stamps

Each\ Page = 5\ stamps

Required

Determine the number of full page

To do this, we simply divide the total stamps by stamps in each page;

Pages = \frac{Total\ Stamps}{Each\ Page}

Pages = \frac{617}{5}

Pages = 123.4

Then we record only the quotient

The quotient is the digits before the decimal

Pages = 123

<em>Hence, she has 123 full pages</em>
