51(x - 21) = x + 58

Distributive property

51x - 1071 = x + 58

Subtract x from both sides

50x - 1071 = 58

Add 1071 to both sides

50x = 1129

Divide both sides by 50

x = 22.58

Steven purchases a bowl. THe diameter of the bowl is 14cm. What is the area of the bowl?

stellarik [79]

Answer: 153.86cm

Step-by-step explanation:

A bowl represents a circle

Area of a circle is pir2

But here we are given the diameter as 14

Diameter = 2radii

14=2r

R=14/2

R=7

So radius of the bowl is 7cm

Back to the formula

Area of a circle is pir2

Pi=3.14

Substitute for each value

Area= 3.14×7^2

Area= 3.14×49

Area= 153.86cm

Area= ~154cm
