The area of the semicircle = 8π

A semicircle is formed when the panel passing through the center touches both ends of the circle. Therefore, if you connect two semicircles, you get a circle

If you cut them in half or divide the circumference of the circle by 2, you will get a semi-circle. Area of semicircle The area of the semicircle is half the area of the circle. Because the area of the circle is πr2. Therefore, the area of the semicircle is 1/2 (πr2). Where r is the radius. The value of π is 3.14 or 22/7.

Semi-circular area = 1/2 (πr2)

One day I found a strange thing happening to my watch,the minute hand & the hour hand were coming together every 65 minutes.

brilliants [131]

Answer:

Step-by-step explanation:

The minute hand of a clock overtakes the hour hand at intervalsof M minutes of correct time. The clock gains or loses in a day by=(720/11−M)(60×24/M) minutes.

Here M = 64. The clock gains or losses in a day by

=(720/11−M)(60×24/M)=(720/11−64)(60×24/64)

=16/11(60×3/8)=2/11(60×3)=360/11=32(8/11) minutes.

What is the slope of 1.5x+4.5y=18

melomori [17]

Answer:

The x intercept is (12,0)

Step-by-step explanation:

1.5x+4.5y=18 Subtract 1.5 x from both sides of the equation

4.5y=-1.5x+18 Divide both sides of the equation by 4.5

4.5y/4.5=-1.5x/4.5+18/4.5

y=-1/3x+4

The slope is -1/3

The y intercept is (0,4)

To find the x intercept, yet y=0 and solve.

1.5x+4.5y=18

1.5x+4.5(0)=18

1.5x=18 Divide both sides of the equation by 1.5

1.5x/1.5=18/1.5

x=12

If you are adding two fractions that are both greater than 1/2, what must be true about the sum? Give three examples to support

anastassius [24]

Answer:

Step-by-step

The sum must be greater than 1 because

1/2 + 1/2= 2/2 or 1

3/4 + 8/4= 11/4

9/16+15/16=24/16

8/8+9/8=17/8

In a young woman's study group, 7 percent of the students are from the town where the young woman's school is located, 80 percen

Umnica [9.8K]

Answer: the percent of study group students from outside the state is 13%

Step-by-step explanation:

The total number of students in the young woman's study group that are from the town where the young woman's school is located is 7%

The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.

Since the rest are from outside the state, the percent of study group students from outside the state would be

100 - (80 + 7) = 100 - 87 = 13%
