The formula for area of a circle is Area = PI x r^2
The radius (r) is given as 9 meters.
The value of PI is given as 3.14
Area = 3.14 x 9^2
Area = 3.14 x 81
Area = 254.34 m²
Mark drove for 5 hrs
pranav drove for 3 hrs
Distance = speed x time
Pranav =50kmh x 3hrs
= 150 km
* note that they drove the same distance
Speed of mark=distance / time
=150 km / 5hrs
= 30 kmh
22? That’s what I would put but it might be wrong.
Hello! I would love to help!
Alright! We know that perimeter is basically adding all the sides of a shape together. We also know that a square has 4 sides, so 38 is the result of 4 sides being added. Now, we also know that all sides of a square are even. So, to find one side of a square, we just need to do 38/4
38/4=9.5
Alright. So now we know one side of a square is 9.5 in. We know that in order to find area, we have to multiply length and width. We know that since all sides of a square are even, 9.5 is both our length and width. So, in order to find the area, we just have to multiply 9.5 by 9.5
9.5*9.5=90.25
Alright! So we have determined your answer!!!
90.25 or in fraction form 90 1/4 inches squared!
Hope this helped! Comment if you have questions!!
Let the yellow corn be x
And other variety be y
Question says that she brought a dozen (as total)
So,
x +y = 12
If cost of yellow corn was 40 cent and cost of other varieties were 50 cents then,
(After changing those cents into dollar)
0.40x+ 0.50y = 5.70
Because she paid a total of 5 dollar 70 cents for yellow and other variety.
So, option "a" is correct.
