The diameter of the circle is 14 units

14pi

Circumference = 48.262

area = pi*r*r r = diameter/2 r=7 7*7 = 49 49pi, or 153.9380400258998686846695257807 sq in

The volume of a cone is 1/3Bh. 1/3(49pi)(11) is approximately 564.4394 u.2.

You can multiply 49 by 2. thus finding the answer or ask someone really smart

14pi

49pi-36pi= 13pi= 40.8 square inches

Circumference = 48.262

The circumference of a circle with an area of 49pi inches2 is about 43.98 inches.

area = pi*r*r r = diameter/2 r=7 7*7 = 49 49pi, or 153.9380400258998686846695257807 sq in

circumference=pi(dimeter)c=pi(49)49pi mior 49 (3.14159265)so 153.93804 miis your answer!youre welcome:]

Pi-R-Squared. pi*R^2 That's the formula for area of a circle, where R=radius. For R=7 the formula gives 49pi. Some calculators have pi buttons, but estimating pi=3.14 is often close enough for real-world application. 49*3.14 = almost 154 square feet.

Assuming 14 is the diameter of the circle, you would use the equation pi(r)^2 to find pi(7)^2 is your answer. Don't have a calculator, so I'm gonna say 49pi is your final answerpi is about 3.14, doing it by hand...3 * 49 = 147.1 * 49 = 4.9.04 * 49 = 1.96Adding 147, 4.9, and 1.96 gives 153.86 square feet.Using a calculator, with more digits of pi gives 153.9380
