A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 31 ft long and 24 ft wide. If

garik1379 [7]

Step-by-step explanation:

First, find the perimeter of the rectangle;

1) perimeter = 2length + 2 width

2) 2(31) + 2 (24) = 110ft

Second, find the circumference of the circle;

1) C = 2πr

2) Since the rectangle is joined to the semicircle, we can assume the diameter is equal the width (or length) of the rectangle. The radius (r) is half of the diameter. (length: r = 15.5 or width: r = 12)

So, C = 2(3.14)(15.5) = 97.32ft

C = 2(3.14)(12) = 75.36ft

Since it is a semicircle, we only need half of its circumference.

97.32 / 2 = 48.66

75.36 / 2 = 37.68

Finally, we are going to add up our values;

1) If the semicircle is on the length of the rectangle (remember to subtract the length of width that semicircle attaches to because we won't need fencing there)

(110-31) + 48.66 = 127.66ft

2) If the semicircle is on the width of the rectangle (remember to subtract the length of width that semicircle attaches to because we won't need fencing there)

(110-24) + 37.68 = 123.68ft

Step-by-step explanation:

$\sqrt{36} < \sqrt{40} < \sqrt{49}$

So sqrt(40) lies between 6 and 7.

Step-by-step explanation:

This javascript code is extremely brute-force, but it does the job:

function checkIfInSet(i, set) {

return i.toString().split('').sort().join('') === set;

}

function checkIfMagic(s) {

return (parseInt(s[0]) + parseInt(s[1]) == parseInt(s[3]) + parseInt(s[4]))

}

function printMagic(s) {

console.log(`${s[0]} ${s[4]}`);

console.log(` ${s[1]} ${s[3]}`);

console.log(` ${s[2]}\n`);

}

function checkSet(set) {

let counter = 1;

for(let i=1; i<99999; i++) {

if (checkIfInSet(i, set) && checkIfMagic(i.toString())) {

console.log(`--${counter++}-- (of set ${set})`);

printMagic(i.toString());

}

checkSet('23456');

checkSet('34567');
