Question

What is the radius of the grape? Round to the nearest tenth of a centimeter.

Answer 1

Answer:

The average radius of the grape is about 1.3 cm, rounded off to the nearest tenth of a centimeter.

Step-by-step explanation of how to calculating the average radius of a grape:

Step 1: Measure the circumference a grape

- Take about 2 to four grapes

- Measure each of the grape's circumference by using a string.

This is done by taking the string around the grape and measuring this length against a ruler.

- Find the average of the circumference of these grapes

For instance 3 grapes each with cirmcference of 5 cm, 3cm and 4cm

5 + 3 + 4  / 3 = 4 cm

- The average circumference of a grape should be 4 cm

Step 2: Calculate the diameter of the grape by using the formula:

Circumference  = π × Diameter

Diameter  = Circumference / π

Diameter = 4 cm / 3.142

Diameter = 1.27324 cm

Therefore the average diameter of a grape is about 1.27324cm

Round off to the nearest tenth of a centimeter:

1.27324  ⇒ 1.3 cm rounded of to the nearest tenth of a centimeter

The radius of a grape rounded of to the nearest tenth of a centimeter = 1.3cm
