Isaac is cutting wood to build a clock. He wants the clock to have a long hand that extends from the center to the edge of the clock face. What must the approximate area of the face be if the hand he is using is 7 inches long? Use pi.

Can you guys explain it plz?

anonymous · Answer

ya i will explain

anonymous · Answer

Area= Pi * r(squared)

Area= 3.14 * (6)(squared)

Area= 3.14 * 36

Area= 113.04

anonymous · Answer

If the long hand extends from the center to the edge of the clock face, then it is the circle's radius. The area of a circle is pi(r^2), where r is the radius. Therefore, the area of the clock face is pi(6)^2 = 36pi = 36(3.14) = 113.04 square inches.

anonymous · Answer

radius = 7
area = pi*r^2
        = 3.14*7*7
         = 3.14*49
         = 153.86
