The value of (9.93).0.984

9.77112

Step-by-step explanation:

Given

Required

Evaluate

To get the value of the expression, we simply multiply both together as follows; 9.93 * 0.984

First, take note of the decimal places

9.93 = 2 decimal places

0.984 = 3 decimal places

Remove the decimals and multiply the numbers as follows

   9   9   3

   9    8   4

----------------------

       3    9   7     2

   7  9   4   4

8  9  3  7

-----------------------------------

9   7   7   1   1   2

Add the decimal places

2 decimal place + 3 decimal places = 5 decimal places

Hence, the result is 9.77112 (5 decimal places)

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
