-3r-8(8r+8)=-9(-4+9r)​
natulia [17]

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is  a(b+c) = ab + ac

Now, the steps of solving are shown below:

-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14

Hence, value of r is 7.14 (rounded to 2 decimal places)

The area of a circle is 39.62cm2.<br> Find the length of the radius rounded to 2 DP.
Shkiper50 [21]

Using the formula for area of a circle:

Area = pi x radius^2

Replace area with the given value:

39.62 = pi x radius^2

Divide both sides by pi

Radius^2 = 39.62/pi

Radius^2 = 12.62

Solve for radius by taking the square root of both sides

Radius = sqrt(12.62)

Radius = 3.55 cm
