Answer:
<u>13.2 centimeters</u>
Step-by-step explanation:
<u>Finding the missing side</u>
- (?)² + (9)² = (16)²
- ?² + 81 = 256
- ?² = 175
- ? = √175
- ? = <u>13.2 centimeters</u>
Answer:
Circle
Step-by-step explanation:
if square plus circle is triangle then if you subtract a square from it all you have left is a circle
The area of the circle is given as:
Plugging the value of the radius we have that:
Therefore the area in terms of pi is:
Answer:
Step-by-step explanation:
A. 4.2E6 because when putting a number into scientific notation, you would want one number in front of the decimal place and then the trailing numbers would follow. The exponent or E stand for how many numbers are after the decimal, which in this case would be 6.
4,200,000 → 4.2 x 10^6 which is equal to saying 4.2E6
Tip: If the exponent is negative than the decimal would go in the opposite direction. For example:
4,200,000 → 4.2 x 10^-6 would not equal each other because 4.2 x 10^-6 means 0.000004, six numbers would be behind the decimal.
Answer:
9 yards
Step-by-step explanation:
A square has 4 equal sides, this means the 2 sides we will multiply to get the area are going to be the same. Since it says 81 yards squared and the shape is a square, we can do the square root of 81 which is 9.
