Bianca filled 2 same-sized jars with flavored popcorn as a gift. She wants to glue a piece of ribbon around the edge of each lid.

The radius of each jar lid is 5 centimeters. Approximately what is the total length of ribbon she will need for the two jar lids? (Use 3.14 for pi .)
A.
157 cm
B.
78.5 cm
C.
31.4 cm
D.
62.8 cm

D

Step-by-step explanation:

You have to multiply 2 times pi.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
