Question

Mary has a planting pot with a circumference of 92 cm. If a plants' directions state that it must be planted directly in the middle of the pot, what would be the exact measurement? Hint: Find the radius.

24.64 cm
14.64 cm
19.64 cm
22.64 cm

Answer 1

14.64 cm

Explanation:

The circumference of a planting pot = 92 cm

To find the measurement of the plant which is planted directly planted in the middle of the pot, we need to find the radius of the planting pot.

We know that the formula of the circumference of a circle is:

Circumference =
`2\pi r`

Therefore, putting the value of the circumference in the formula to get:

92 = 2 x 3.14 x r

r = 92 / (3.12 x 2) = 14.64 cm

Therefore the plant is 14.64 cm long.

Answer 2

14.64 cm

Explanation:

this problem is finding radius of a circle from the circumference given.

Circumference of a circle = 2(3.14) r

Using the above we can find one if we know the other. In our case we know circumference and calculate radius.

Circumference = 2(3.14)r= 92 cm

Hence r = 92/2(3.14) = 14.6497cm

apprxoximately 14.64 cm is close to the answer

Hence answer is 14.64 cm.
