ANYBODY PLEASE HELLP (: ?

(a) Area: 530.66 ft^2

    Circumference: 81.64 ft

(b) Circumference

(c) Area

Step-by-step explanation:

(a) Use the area formula of a circle: A = pi*r^2

A = 3.14*(13)^2 = 530.66 ft^2

Use circumference formula of a circle: C = pi*d or 2pi*r

C = 3.14*26 = 81.64 ft

(b) If you are putting tape that covers the outside, then you would need the circumference of the lawn

(c) If you are placing fertilizer, you would need to find the area of the lawn

Hope this helps :)

55/i dont know i do it for the points

step-by-step explanation:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
