Answer:

530.66

Step-by-step explanation:

The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14

For this circle we do 3.14 * 13^2

First we have to square 13: 13^2 = 169

Then we multiply 169 by 3.14: 3.14 * 169 = 530.66

Then we do to the nearest hundredth which is the same as the previous answer: 530.66

Make x the subject of these equations.
shepuryov [24]

(1)a(x + b) = c \\ ax + ab = c \\ ax = c - ab \\  \frac{ax}{a } =  \frac{c - ab}{a}   \\ x =  \frac{c - ab}{a}

(2)8(x + a) = b \\ 8x + 8a = b \\ 8x = b - 8a \\  \frac{8x}{8}  =  \frac{b - 8a}{8}  \\ x =  \frac{b - 8a}{8}

(3)a(x - 7) = b \\ ax - 7a = b \\ ax = b + 7a \\  \frac{ax}{a}  =  \frac{b + 7a}{a}  \\ x =  \frac{b + 7a}{a}

(4)c(2  + x) = 6 \\ 2c + cx = 6 \\ cx = 6 - 2c \\  \frac{cx}{c}  =  \frac{6 - 2c}{c}  \\ x =  \frac{6 - 2c}{c}
