Answer:
16π m2
Step-by-step explanation:
The area of a sector (A) is given by:

Where
is the angle of the sector
r is the radius of the circle
<em>We can see that the angle of the sector is 90, and the radius of the circle is 8. Plugging these into the formula, we get:</em>

The area is 16π m2
Answer:
the correct option is<u> d) 72</u>
Step-by-step explanation:
The given expression is 
first multiply numerator and then solve the fraction


solve the fraction,

∴The equivalent expression of
is 72
Hence, the correct option is<u> d) 72</u>
The sum (+) of 14 and a number (x) is equal to (=) 7.
14 + x = 7
To solve, subtract 14 from both sides.
x = -7
You need to fine the radius by dividing the circumference by 2 and then multiply that by pi (3.14) or (22/7)
