Estimate the area of a circle with a radius of 16 meters. Use 22/7(fraction) for pi. Help

22/7(16^2) = about 805 meters squared. 2. Let's find the area of the rectangle first. A=LWA= 18(10)A= 180 cm squared. Now the semi-Circle:The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:127 cm squared for the semi-circle. Now we add up the rectangle and semi-circle's areas:180 + 127 = 307 cm squared as your answer.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
