What is the area of a circle with a diameter of 10ft? Use 3.14 for pi.
Answers
Answer:
B) 78.5
Step-by-step explanation:
The formula for the area of a circle is :
To work this out you would first need to divide the diameter of 10 by 2, which gives you 5. This is because in order to calculate the area you would need to work out the radius. The radius of a circle is half of the diameter.
Then to work out the area you would multiply pi by the radius of 5 squared, this gives you 78.54 square feet.
1) Divide 10 by 2.
2) Multiply pi by the radius squared.

we must add the 2 expressions

Answer:
A. 5 minutes
Step-by-step explanation:
We can solve this question using proportions
Let x be the number of minutes needed to type 225 words.
8 minutes = 360 words
x = 225 words
Cross-multiply
360 × x = 225× 8
360 x = 1800
Divide both-side of the equation by 360
=
(On the left-hand side of the equation, 360 at the numerator will cancel-out 360 at the denominator, while on the right-hand side of the equation 1800 will be divided by 360)
x= 5 minutes
Therefore, it will take 5 minutes to type 225 words
Well, it cant be option B because then it wuld be half the time (180 mins.)
It cant be option D becasue then it would be over 360 mins, seeing that it only took 8 mins to type 360
And it cant be option C beacuse it would be too small, if 4 mins is to small then 3 mins is worse
Your answer would be A 5 minutes it's just a little bit above 4 mins(half)
