The area of circle is 379.94 cm².

Step-by-step explanation:

Given,

Radius of circle = 11 centimeters

We have to calculate the area of circle.

We know that;

Area of circle = $\pi r^2$

Here;

π = 3.14 , r = 11

Area of circle = $3.14*(11)^2$

Area of circle = 3.14*121

Area of circle = 379.94 squared centimeters

The area of circle is 379.94 squared centimeters.

A right triangle has a leg length of 12 and a hypotenuse length of 18. What is the length of the other leg?

lord [1]

Answer:

The length of the leg is 13.416

Step-by-step explanation:

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse = 18

a = leg 1 = 12

b = leg 2 =

h² = a² + b²

we replace the known values and solve

18² = (12)² + (a)²

324 = 144 + (a)²

324 - 144 = (a)²

√180 = a

13.416 = a

The length of the leg is 13.416

The perimeter of the blueprint is represented by the equation P=8x. What is the equation of the perimeter when solved for x

Korvikt [17]

Answer:

x = P/8

Step-by-step explanation:

The perimeter of the blueprint is given by the equation :

P = 8x

We need to solve the above equation for x.

Dividing both sides of the equation by 8.

$\dfrac{P}{8}=\dfrac{8x}{8}\\\\x=\dfrac{P}{8}$

Hence, the value of x is P/8
