What is the area of a circle with a radius of 4in?
50.26548 sq. inches.
What is the surface area of a cylinder with a radius of 3in and a height of 4in. Use 3.14 for pi?
Surface area of cylinder is circumference multiplied with height.Surface area = (3 x 2Pi) x 4 = 6 x 3.14 x 4 = 75.36 square inches.
Find the perimeter of the trapezoid below 4in 4in 6in 5in?
4+4+6+5 = 19 inches is the perimeter
What percent larger is the area of a 5in circle as compared to a 4in circle?
The area of a 5-inch circle is: 19.6 square inches.The area of a 4-inch circle is: 12.6 square inches.The area of the 5-inch circle is 55.6% larger than the 4-inch circle
What is the volume of a rectangular prism that has these dimensions 6in 4in 4in?
The volume is 96 cubic inches.
What is the circumference of a circle with a radius of 4in?
circumference = 2*pi*4 inches
What is the area of a circle with a radius of 4in?
50.26548 sq. inches.
What is the radius of a circle that is 4in in diameter?
The radius is a line segment from the center of a circle to any point on the circle. Thus it is half the diameter, and in this case 2in.
If a circle has a radius of 4in how do you get the circumference and area?
Circumference is diameter*π, so the answer is 12.56636 in Area is π*r², so 16π = 50.42544 in² * * * * * Correct formulae, but incorrect answers. Radius = 4 inches implies diameter = 8 inches. So circumference = 8*pi = 25.13 inches. Also, area = pi*r2 = 16*pi = 50.265 sq inches. There is no point in giving the answer to 5 decimal places if you then use 3.15159 for pi instead of 3.14159!
Looking straight down along the verticval axis of the right circular cone in the following find the area of the two dimensional shape that is seen the radius is 4in and height is 10in?
square the radius because all you are able to see is the circle so the answer for this one is 16inches
What is the volume of a sphere with the radius of 4in?
268.0825731 or 268 cubic inches
How do you find the perimeter for 4ft 10in plus 6ft 4in?
Perimeter = 2*(4ft 10in+6ft 4in) = 22ft 4in
What is the surface area of a cylinder with a radius of 3in and a height of 4in. Use 3.14 for pi?
Surface area of cylinder is circumference multiplied with height.Surface area = (3 x 2Pi) x 4 = 6 x 3.14 x 4 = 75.36 square inches.
In a circle whose diameter is 20in and a chord is 6in from the center what is the length of the chord?
the chord is 4in long
Find the perimeter of the trapezoid below 4in 4in 6in 5in?
4+4+6+5 = 19 inches is the perimeter
What is thevolume of a sphere with the radius of 4in?
Volume of a sphere = 4/3*pi*radius3 Volume = 268.0825731 or 268 cubic inches
