Answer:
8^2-60 , 11^1 , 2^2x5
Step-by-step explanation:
2^2= 4
4 x 5 = 20
11^1= 11
8^2= 64
64-60 = 4
Answer:
7.) 53.38
8.) 18.84
9.) 87.92
Step-by-step explanation:
7.)
For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.
The formula for finding the circumference is 2 × π × 8.5
2 × 3.14(π) = 6.28.
6.28 × 8.5 = 53.38
8.)
For the second question, we can see that the radius is now given to us which is 3ft.
The formula for finding the circumference is 2 × π × 3
2 × 3.14(π) = 6.28.
6.28 × 3 = 18.84
9.)
For the third question the raduis is also given to us, which is 14 in.
The formula for finding the circumference is 2 × π × 14.
2 × 3.14(π) = 6.28.
6.28 × 14 = 87.92
