Answer:

The area of the semicircle having a radius of 19.6 meters is

603.68 m^{2}.

Detailed Answer:

The formula for the area of a circle is πr^{2}. Therefore, the formula for the area of a semi-circle is (\frac{1}{2} πr^{2}).When the calculation is done

\frac{1}{2} ×\frac{22}{7} × 19.6 × 19.6 = 603.68 meters squared.

In order to solve how many problems each person has solved, you have to multiply the fraction by the number of problems on their assignment. To do this, you multiply the numberator by the number of problems and then divide that by the denominator for both Dustin and Kelsey.

For Dustin, 3/8 * 24 = 72 / 8 = 9 problems completed

For Kelsey, 4/15 * 30 = 120/15 = 8 problems completed

Dustin has completed more problems

What following number is in between 2/5 and 7/8?<br><br> 15/16, 3/4, 3/8, 1/3
Setler [38]

Answer:

Step-by-step explanation:

You need to give all the fractions a common denominator so you can compare the numerators.

The least common multiple of 5, 8, 16, 4, 3 is 240.

⅖ = 96/240

⅞ = 210/240

15/16 = 225/240

¾ = 180/240

⅜ = 90/240

⅓ = 80/240

The only numerator between 96 and 210 is 180.

180/240 = ¾

⅖ < ¾ < ⅞
