A circular rug has a radius of 10 feet. What is the area of the rug? Use 3.14 for π. Enter your answer 31.4

The rug has an area of 314 feet²

Step-by-step explanation:

Area of a circle = pi * radius²

pi = 3.14

radius = 10 feet

Area of a circle = 3.14 * 10²

Area of a circle = 3.14 * 100

Area of a circle = 314 feet²

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
