Question

question 1 (5 points)what is the circumference of the circle below? use 3.14 for pi. remember $c=2\times3.14\times r$10 in.a 31.4 inchesb 62.8 inchesc 328 inchesquestion 2 (5 points)what is the approximate area of the circle below? use 3.14 for pi. remember $a=3.14\times r^2$20 in.a 125.6 square inchesb 1256 square inchesc 5024 square inches

Explanation:

Step1: Identify radius for Q1

Radius $r = 10$ in.

Step2: Apply circumference formula

$C = 2 \times \pi \times r = 2 \times 3.14 \times 10$

Step3: Calculate Q1 result

$2 \times 3.14 \times 10 = 62.8$

Step4: Identify radius for Q2

Radius $r = 20$ in.

Step5: Apply area formula

$A = \pi \times r^2 = 3.14 \times 20^2$

Step6: Calculate Q2 result

$3.14 \times 400 = 1256$

Answer:

Question 1: b. 62.8 inches
Question 2: b. 1256 square inches
