What is the area to the nearest tenth of a square foot if the circumference of a circle is 16.5 feet?
The area of a circle with radius r is A = pi.r^2. The radius of a circle with circumference C is r = C/(2pi) since C=2.pi.r. So the radius of a circle with circumference 16.5 feet is r = 16.5/(2pi) ≈ 16.5/(2x3.1416) ≈ 2.626 feet. Thus this circle has area A = pi.r^2 ≈ 3.1416 x (2.626)^2 ≈ 21.7 square feet.
What is the area of a circle if the radius of a circle is 3.7cm?
The formula for finding the area of a circle is : pi(r) squared. So, that answer would be 13.69cm multiplied by pi, which is nearest to 3.14.

3.0
What is area to the nearest tenth of a 120 degree sector of a circle with radius of 8 ft?
Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.

Area of a circle = (pi) x (radius)2 = (pi) x (4)2 = 16 pi = 50.3 in2 (rounded)
What is the area of a circle with the radius of 15 milliter to the nearest 10th?
If I remember correctly Area of a circle is... PIE multiplied by the RADIUS squared. If this is so.... 15 is the radius and... The sum of 15 x 15 should be multiplied by pie (3.1415 or what ever it is). Use a calculator to get to the nearest tenth.
