Find the area and the circumference of the circle with the radius 6yd.

fgiga [73]

Answer:

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

The formula of a circumference of a circle:

$C=2\pi r$

r - radius

We have r = 6yd.

Substitute:

$A=\pi(6^2)=36\pi\ yd^2$

$C=2\pi(6)=12\pi\ yd$

If you want round the answers, then use π ≈ 3.14

$A\approx(36)(3.14)=113.04\ yd^2$

$C\approx(12)(3.14)=37.68\ yd$

A triangle with sides 11m , 13m and 18m is a right triangle. A True B False

Julli [10]

$\bold{\huge{\pink{\underline{ Solution}}}}$

$\bold{\underline{ Given :-}}$

A triangle with sides 11m, 13m and 18m

$\bold{\underline{ To \: Find :-}}$

We have to check it whether it is right angled triangle or not?

$\bold{\underline{ Let's \: Begin :-}}$

$\sf{\red{ In \:right \:angled\ : triangle, }}$

According to the Pythagoras theorem, The sum of the squares of perpendicular height and the square of the base of the triangle is equal to the square of hypotenuse that is sum of the squares of two small sides equal to the square of longest side of the triangle.

We imply it in the given triangle ,

$\sf{\red{ ( Perpendicular)² + (Base)² = (Hypotenuse)²}}$

$\sf{(AB)² + (BC)² = (AC)²}$

$\sf{ (11)² + (13)² = (18)² }$

$\sf{ 121 + 169 ≠ 324 }$

$\sf{ 290 ≠ 324 }$

From Above we can conclude that,

The sum of the squares of two small sides that is perpendicular height and base is not equal to the square of longest side that is Hypotenuse

$\sf{\blue{ Hence,\: Your\: answer \:is \:false }}$

Justine bought a pair of boots for $76.68 and paid 13% sales tax. What was the price of these boots including tax?

MArishka [77]

Answer: $86.65

Step-by-step explanation:

First, find how much Justine paid in tax. To do this, first convert 13% to a decimal by dividing by 100. This gets a tax rate of 0.13. Now, multiply the price of the boots by the tax rate. 76.68*0.13 = 9.9684. Round to the nearest cent to get $9.97.

Now, add the amount paid in tax to the price of the boots. 76.68+9.97 = $86.65.
