9.find the area of the parallelogram with a base of 471.5 cm and height of 21.3
and the choose options are these:
~492.8 cm and exponent of 2
~10,04295 cm with a exponent of 2
~20,085,9 cm exponent of 2
~985,6 cm and exponent of 2.
492.8 cm exponent of 2 i got wrong and it says this on the test that 10,042,95 cm and exponent of 2 is Right. and i need to show how i got the answer step by step and please help me as soon as possible. please and thank you so much y'all.
sorry.
i don't need help anymore. with that question
The circumference of mars is about 10,664 km. find the diameter of mars to the nearest km.
the answer chose's are these:
17.256\3,396/333/259
17.256 i got wrong and
3,396 is right and i need step by step how to solve this. question.
Circumference = πd, where d is the diameter
10664 = πd
d = 10664/π = appr 33502 km
thanks so much.
To find the area of a parallelogram, we can use the formula: Area = base x height.
In this case, the base is given as 471.5 cm and the height is 21.3 cm. Let's substitute these values into the formula to calculate the area.
Area = 471.5 cm x 21.3 cm
To multiply these numbers, we can simply multiply the digits without the units first and then include the units at the end.
Multiplying 471.5 by 21.3:
471.5
x 21.3
--------
94300
+ 23575
--------
100875
So, the product of 471.5 and 21.3 is 100,875.
Therefore, the area of the parallelogram is 100,875 cm^2.
The correct option among the given choices is "~10,042,95 cm with an exponent of 2".
I hope this helps! Let me know if you have any further questions.
