Question

find the length of the radius, the circumference, and the area of the circle. use 3.14 for pi. the diameter is 29.7cm
(simplify your answer. type an integer or decimal)

Answer 1

First, radius is half of the diameter, so do 29.7/2 to get the radius.

Answer 2

i know c=2xr*3.14
the area=3.14*r^2

Answer 3

\[\color{green}{1. \quad Radius = \frac{Diameter}{2} \\ 2. \quad Circumference = 2 \times \pi \times Radius \\ 3. \quad Area = \pi \times (Radius)^2}\]

Answer 4

You need to find Radius to find the other two...
Find the radius first of all @marihelenh told you to...

Answer 5

how to simplify if the radius is 14.85

Answer 6

Then the equation for circumference is C=2(pi)r and area equals A=(pi)r^2.

Answer 7

You can take it as 14.85 itself...

Answer 8

Do the approximation at the last...

Answer 9

WOULD IT be cm or cm^2

Answer 10

Circumference is cm. Area is cm^2.

Answer 11

or cm3

Answer 12

For Circumference, it will be cms only..
And for area, cm^2..

Answer 13

so the circumference is 93.258

Answer 14

would the radius be cm or cm2 or cm3

Answer 15

Radius will be in cms, diameter will be in cms, circum in cms and area will be in cm^2..

Answer 16

so my answer for the area is 692.44065 how to simplify it
the circumference is 93.258 how to simplify that

Answer 17

The problem should tell you how it wants you to simplify. If it doesn't say, you probably do not need to worry about simplifying.

Answer 18

ok it just says simplify (simplify your answer. type an integer or decimal)
