Answer:
First you find the radius R
We have, circumference = 2*3.14*R = 31.4
=> R =31.4/(2*3.14) =5
We have , area = 3.14*R^2 = 3.14*5^2 = 78.5
Step-by-step explanation:
Here we use pi =3.14.
24 square inches. do the area of the whole rectangle (7x12) and subtract the two little rectangles (5X6) x 2= 60 so 84-60=24
Answer:
B
7! = 7 X 6 X 5 X 4 x 3 x 2 x 1
Step-by-step explanation:
n! is the product of all natural numbers until n
7! = 1 × 2 × 3 × 4 × 5 × 6 × 7
