Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
a stop sign has eight sides. ten times eight is eighty, therefore the awenser is eighty inches
The area of any shape should be in SQUARE unit, and not only unit. So the question is wrong!
It will travel ten feet.
Ten minutes is too long ( a time). The sentence Ten minutes are too long means that ten of the minutes are longer than the others.
If ten inches is the diameter, the circumference is 31.4159 inches.
Because C=Ï€.d the answer is 3,183 in.
A circle that is ten feet in diameter has a circumference of (approximately) 31.4 feet.
The circumference of a circle if the diameter is 10 feet long is: Pi x 10 (about 31.416).
1.9 and the diameter is ten
The area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches is: 25 square units.
Circumference = pi * diameter = 3.14159 * 11.6 = 36.44 Rounded to the nearest ten, that is 40 units.
Circumference=Diameter*pi so plug in 10 = Diameter * pi and solve. I hope you can do this by your self from here
The area is 78.5 square inches.
Use the equation for circumference: C = pi * d Plug in 10 inches for "d" => C = 3.14 * 10 inches = 31.4 inches 31.4 inches is the circumference of a dinner plate with a diameter of 10 inches. Key: C = circumference d = diameter pi = 3.14
The circumference of a circle is pi x diameter, where pi equals approximately 3.14. Therefore, the inner circumference of a brick circle with an inside diameter of 10.5 feet is 32.99 feet. As a result, 33 one foot bricks would create a circle with a diameter slightly larger than 10.5 feet, without any gaps between the bricks.
Area = pi R2 = 25 pi = 78.54 square inches (rounded)
