19.625cm squared because you have to divide the diameter by 2 to get the radius.
Area of circle = pi times radius times radius
= 3.14 times 2.5 times 2.5
= 19.625cm squared
Answer:
B.The exponent of the solution is –12, the difference of the original exponents.
C.The coefficient of the solution must be greater than or equal to one but less than 10.
D.The quotient is 3.0 ×
Step-by-step explanation:
To solve this all you need to do is do the opposite of multipulcation:
1590/5
Which equal 318. To check you answer do 318×5
Well if you divide 7 divided by 12 you get 0.583 which you can round however you wish but I am not sure if that’s what you mean
