Answer:
11,200
Step-by-step explanation:
At first we use "BODMAS" rule.
Given,
(3.5×10^13)-(1.4×10^12)/3×10^9
So, we will break the brackets at first. With the help of excel, we can get the desired result. The following images will show you the step-by-step result.
Use "Number" instead of "general" in the excel sheet. You can use calculator too.
Answer:
The area of the shaded sector is
Step-by-step explanation:
I assume that the problem is
Find the area of the shaded sector of the circle with radius equal to 16 units
step 1
Find the value of x
we know that
-----> by complete circle
The central angle of the shaded sector is 2x
step 2
Find the area of the circle
The area of the circle is equal to
we have
substitute
step 3
Find the area of the shaded sector
we know that
A central angle of 360 degrees subtends an area of circle equal to
so
by proportion
Find the area of the shaded sector by a central angle of 72 degrees
