Answer 1

Answer:

A woman’s basketball has a circumference between 72 and 74 centimeter and a maximum weight of 570 grams.                                                                

Step-by-step explanation:

We are given the following in the question:

A woman’s basketball has a circumference between 28.5 and 29.0 inches.

We have to convert this measurement into centimeters.

Conversion:

1 inch = 2.54 centimeter

$1\text{ centimeter} = \dfrac{1}{2.54}\text{ inch}$

$28.5 \text{ inch} = 28.5\times 2.54 = 72.39 \approx 72\text{ centimeter}$

$29.0 \text{ inch} = 29.0\times 2.54 = 73.66 \approx 74\text{ centimeter}$

Thus, the basketball has a circumference between 72 cm and 73 cm.

A woman’s basketball has a maximum weight of 20 ounces.

We have to convert this measurement into grams.

Conversion:

1 ounce = 28.3495 grams

$20 \text{ ounces} = 20\times 28.3495 = 566.99 \approx 567\text{ grams}$

Since we want the answers upto two significant figure, the maximum weight of basketball is 570 grams.
