Step-by-step explanation:

Given:

Radius = 10 ft

pi = 3.14

To Find:

The area of a circle = ?

Solution:

A = pi x r^2

A = 3.14 x (10)^2

A = 3.14 x 100

A = 314 sq. ft

Therefore,

The area of a circle = 314 sq. ft

Solve the equation -4x + 7 y equals 20. Y=3x+15

satela [25.4K]

Substitue what y equals for y and solve.

$-4x+7(3x+15)=20 \\-4x+27x+105=20 \\23x=-85 \\x=-\boxed{\frac{85}{23}}$

Hope this helps.

6,500 acres of a 41,000 acre forest burned in a fire. what percentage of forest was damaged?

Tems11 [23]

Answer:

15.85%

Step-by-step explanation:

Given:

Acres damaged (burned) = 6,500 acres

Acres in total forest = 41,000 acres

Hence the amount of damaged forest as a fraction of the total forest,

= $\frac{6500}{41000}$ = $\frac{13}{82}$

expressed as percentage = $\frac{13}{82}$ x 100% = 15.85%
