HEY THERE !!
As we know that the area of a circle (A)= πr^2
But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}
Here diameter is 10.5 inches.
A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}
So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.
HOPE IT HELPED YOU.
I remember doing this question. The question went like:
<span>1.25x + 1.49 = 100
What error did Barbara make in writing the equation?
And the answer would be that Barbaras equation did not consider the number of ice tea drinks. Hence, </span>She put the correct price in the equation but she didn't put the (x) number of iced tea drinks. In other words,This is because she has added 1.25 X the number of water bottles sold to 1.49, the cost of one iced tea.
So, the correct equation would be:
1.25x +1.49y = 100
Would really appreciate if you would put me as Brainliest answer.
