Question

question 4 not yet answered marked out of 1.0 flag question wilma measured the radius of a circle and (correctly) got a length of 14 cm. if pebbles used this information to determine the area of a circle, she will get an area of? question 5 not yet answered marked out of 1.0 flag question what is the area of a circle that has a radius of 4 cm. use \\(\pi = 3.14\\) and round to the nearest \\(\text{cm}^2\\). select one: a. the area of the circle is 25 \\(\text{cm}^2\\). b. the area of the circle is 39 \\(\text{cm}^2\\). c. the area of the circle is 201 \\(\text{cm}^2\\). d. the area of the circle is 50 \\(\text{cm}^2\\). e. the area of the circle is 13 \\(\text{cm}^2\\).

Explanation:

Step1: Recall circle area formula

The area of a circle is $A = \pi r^2$
---

For Question 4:

Step1: Identify given radius

$r = 14$ cm, $\pi = 3.14$

Step2: Calculate squared radius

$r^2 = 14^2 = 196$

Step3: Compute area

$A = 3.14 \times 196 = 615.44$ cm²
---

For Question 5:

Step1: Identify given radius

$r = 4$ cm, $\pi = 3.14$

Step2: Calculate squared radius

$r^2 = 4^2 = 16$

Step3: Compute area

$A = 3.14 \times 16 = 50.24$

Step4: Round to nearest whole number

$A \approx 50$ cm²

Answer:

Question 4: $\boldsymbol{615.44}$ cm²
Question 5: $\boldsymbol{d. The area of the circle is 50 cm^2}$
