Mathematics
1 answer:
Helen [10]3 years ago

Answer:

530.66 cm²

Step-by-step explanation:

First, since the formula for the area of a ball is r² x 3.14, you multiply 13 by itself. Since 13x13 is 169, you do 3.14x169. Your answer should be 530.66 cm². (i don't know what the other one is, or if it's just a separate question.)

The perimeter of a rectangular field is 264 yards. If the width of the field is 54 yards, what is its length?
SIZIF [17.4K]
P = 2(L + W)
P = 264
W = 54

264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards
