Acircular lid on a to-go cup has a diameter of 4 inches. what is the area of the lid to the nearest hundredth? (use 3.14 as an approximation of pi.)

a.) 12.56 square inches
b.) 25.12 square inches
c.) 50.24 square inches
d.) 62.80 square inches

m!

The answer is A) 12.56 square inches

Step-by-step explanation:

The equation to find the answer is 3.14×r²

r standing for radius. To find the diameter, you simply multiply the radius by 2.

Because they already gave us the diameter, the equation to solve this question is 3.14×4

3.14×4=12.56

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
