Find the area of the circle to the nearest tenth. use 3.14 for pie
VikaD [51]
I assume that 4.4 is the diameter,please do correct me if i am wrong.

To get the area of the circle,the formula is 丌r^2

to find the radius,we need ro devide the diameter by 2

thus the equations is
3.14  \times  ({4.4 \div 2})^{2}  \\  = 3.14 \times {2.2}^{2}  \\  = 15.196 \\  = 15.2(correct \: to \: the \: nearest \: tenth)
Therefore the answer is B.15.2

hope it helps!

Yuliya22 [10]

Answer:

The total price of the Rice sack is Rs 1920.

Step-by-step explanation:

The price of 1 sack of rice = Rs. 1,850

Wages Charge = Rs. 70

Now, the total price = Price of the Rice + Wages Charge

= Rs. 1,850 + Rs. 70

= Rs. 1920

or,  the total price = Rs. 1920

Hence, the total price of the Rice sack is Rs 1920.
