Find the area of the following circles. a. a circle with a 8-inch radius b. a circle with a 10-kilometer radius c. a circle with a 14-yard diameter d. a circle with a 22-centimeter diameter

Area of a circle is .  The first one, a, the radius squared is 8*8=64.  So .  If you multiply in pi as 3.14, you'll have 200.96 square inches.  The second one, b, the radius squared is 10*10=100.  So square kilometers.  If you multiply in pi as 3.14 you'll have 314 square kilometers.  The third one, c, the radius squared is 14*14=196.  So .  Or you could multiply in pi as 3.14 to get 615.44 yd squared.  For the last one, d, the radius squared is 22*22=484 cm.  Therefore, , or multiply in 3.14 for pi to get 1519.76 cm squared.  There you go!

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
