The area of the circle is 28.26 in²
<u>Explanation:</u>
Given:
Radius of the circle, r = 3 in
Area of circle, A = ?
We know:
Area of circle = πr²
The value of π is 3.14
Thus,
A = 3.14 X (3)²
A = 3.14 X 9
A = 28.26 in²
Therefore, the area of the circle is 28.26 in²
Answer and Step-by-step explanation:
A Quarter is equal to 25 cents.
A Nickel is equal to 5 cents.
We have 4 quarters and 8 nickels, so times this amount of coins to their values.
4 × 25 = 100
8 × 5 = 40
Now, we add these together.
140.
This is 140 cents.
After the 100 mark, it turns into a dollar (because there is 100 pennies (cents) in 1 dollar).
So that means the total amount of money we have is One dollar and Forty cents ($1.40)

Answer:
$3.60, $21.60
Step-by-step explanation:
if 3/4 of 1grape = $2.70
Then
1grape = 2.70 ×4/3
1grape = $3.60
Therefore
6grapes = 3.60 × 6
= $21.60
Answer:
13 , 17 and 25 cm.
Step-by-step explanation:
Let the length of the first side be x cm.
Then the second is x+4 and the third is 2x-1 cm long.
As the perimeter = 55 cm we have the equation:
x + x + 4 + 2x - 1 = 55
4x + 3 = 55
4x = 52
x = 13 cm.
