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

Find a whole number x in x/113 so that the ratio is a good estimate for pi
NISA [10]
So the initial question is x / 113 = 3.14 (we're keeping it a smaller decimal for now)

What you should do first is multiply both sides by 113

Your answer should be x = 354.82

Round this up to x = 355. <-- This is why we only used 3.14 at the start

Now check your work:
x / 113 = ?
355 / 113 = 3.14159265358979... which essentially is pi
