Answer:

2 square cm

Step-by-step explanation:

Given :

A square is inscribed in a circle whose radius is r = 1 cm

Therefore, the diameter of the circle is 2 r = 2 x 1

                                                                      = 2 cm.

So the diagonal of the square is 2r.

Using the Pythagoras theorem, we find each of the side of the triangle is $r \sqrt 2$.

Therefore, the area of the square is given by $\text{(side)}^2$

                                                                         = $(r\sqrt 2)^2$

                                                                         $= 2 r^2$

                                                                         $= 2 (1)^2$

                                                                         $=2 \ cm^2$

Hence the area of the largest square that is contained by a circle of radius 1 cm is 2 cm square.

A group of farmers had to plough 112 acres of land per day. Exceeding the schedule by 8 acres per day, the farmers finished plow
mihalych1998 [28]

The farmers had to plough a total of 1,456 acres of land.

Step-by-step explanation:

Step 1; The group of farmers ploughed at a rate of 112 acres of land a day which was 8 acres more than schedule.

Scheduled rate = 112 acres per day - 8 acres = 104 acres per day.

So the farmers were supposed to plough 104 acres a day according to schedule.

Step 2; If the farmers finished a day earlier, it means they had to have completed ploughing 104 acres extra by doing an extra 8 acres a day.

So days took to complete ploughing = \frac{104}{8} = 13 days.

So in 13 days, they should have ploughed 13 × 104 = 1,352 acres but due to their increased rate, they ploughed 13 × 112 = 1,456 acres in 13 days.

Difference in acres ploughed = 1,456 - 1,352 = 104 acres.

So the farmers ploughed 1,456 acres in 13 days.

Point N is on line segment MO. Given MO = 3x - 10, NO = x, and M N = 8,
alexandr402 [8]

Answer:

MO = 17

Step-by-step explanation:

First, you need to define what if the unknown x.

segment MN and NO are equal to MO.

thus, your equation for the combination is x +8

Now set the values equal to each other

x + 8 = 3x - 10 (subtract x from both sides)

8 = 2x - 10 ( get your x value alone, add 10 to both sides)

18 = 2x (simplfy)

x = 9

Now plug x value into MO

3 (9) - 10 = 17

Check with opposing equation:

9 + 8 = 17 √
