The first way i.e. the 4(x)
Step-by-step explanation:
Its because there's no gap in between and the letter is surrounded by brackets on both sides so it cant be divided and it's the only letter . There's no rule in mathematics that allows you to multiply a single number surrounded by brackets at both sides.
Answer:
105 mm²
Step-by-step explanation:
The area (A) of the regular polygon is calculated as
A = 
pa ( p is the perimeter and a the apothem )
Here a = 5 and p = 6 × 7 = 42, thus
A = 
× 42 × 5 = 21 × 5 = 105 mm²
Answer:
21
Step-by-step explanation:
To find the area of a cylinder you mutliply radius by height.
r*h = 162
If we know the height is 7.7, substitute it for <em>h.</em>
r*7.7 = 162.
Or:
162 / 7.7
Which gives you 21.03, or 21.
C I believe if I am wrong tell me whats the answer~
Answer:
21
Step-by-step explanation:
Three raise to third power can be written as 
. In this three is the base which is raised to third power.
Next we need to subtract 6 from Three raise to third power(i.e from 27)
which can be written mathematically as
Hence 6 less than three raised to the third power is 21 as explained above.
