The diameter of a circle is 11 m. Find its area to the nearest tenth.

95.0 m²

Step-by-step explanation:

The formula for the area of a circle of radius r is A = πr².

Here the diameter is given and is 11 m; therefore the radius is r = (11/2) m.

Thus, the area of this circle is

A = πr² = π(11/2 m)²  = π(121/4) m², or approx. 95.0 m²

PART A: 28 hours, PART B: 16800 minutes

Step-by-step explanation:

Delia Brushes her teeth =  1/6 hour

PART A

Total Week= 1 week

Total number of  days in a week= 7 days

Total number of hours in a day= 24 hours

Total number of hours in a week= 24× 7 hours

Total number of hours in a  week=  168 hours

Number of hours that Delia brushes her teeth = × 168 hours

Number of hours that Delia brushes her teeth = 28 hours

Hence, the correct answer is 28 hours

PART B

Total number of  days in a week= 7 days

Total number of hours in a  week=  168 hours

Total number of minutes in a  week=  168 × 60

Total number of hours in a  week=  100800 Minutes

Number of minutes that Delia brushes her teeth = × 100800

Number of hours that Delia brushes her teeth = 16800 minutes

Hence, the correct answer is 16800 minutes
