You can use a calculator
Step-by-step explanation:
Answer: 32
1/3 * 32 = 32/3
Step-by-step explanation:
1.The formula in finding the area of a circle is derived from the area of a parallelogram. It is false.
2. The area of a circle is πr² where r is the radius of the circle. It is true.
3. The area of a circle is equal to pi divided by the square of the radius. It is false.
4. The diameter of a circle is equal to twice its radius i.e. d = 2r. It is true.
5. If r = 2.1 m
Area of circle, A = πr²
= 3.14 (2.1)²
= 13.85 m²
Henc,e this is the required solution.
Answer:
option-A
Step-by-step explanation:
We can use rth term binomial expansion formula
we are given
we can compare
n=8
r=4
now, we can find 4th term
now, we can simplify it
