1. Steven purchases a bowl. The diameter of the bowl is 14 cm. What is the circumference of the bowl? 2. Daniel wants to buy cookies for her friend. The radius of a cookie is 5 inches. What is the cookie's circumference? 3. Donna makes a round pizza. She wants to put a cheese layer on the pizza. If the cake is 8 cm in diameter, how many square cm of cheese layer does she need to put on the pizza? 4. Cynthia wants to buy a round photo frame for her brother. The radius of the photo frame is 9 cm. What is the photo frame's circumference? 5. Brian made a tasty burger. The diameter of the burger was 5 cm. What was the area of burger?

1. The circumference of bowl is 43.98 cm

2. The circumference of cookie is 31.42 inches

3. The amount of square centimetre of cheese layer she needs to put on the pizza is 50.27 cm²

4. The circumference of photo frame is 56.55 cm

5. The area of burger is 19.635 cm²

Step-by-step explanation:

1. Bowl diameter = 14 cm

Circumference of bowl = π·D = π×D

Where:

D = 14 cm

Circumference = π × 14 = 43.98 cm

2. Radius of cookie, r = 5 inches

Circumference of cookie = π·D = π×2×r = π×2×10 = 31.42 inches

3. Diameter, D of pizza = 8 cm

Area of pizza = π·D²/4 = π·8²/4 = 50.27 cm²

The amount of square centimetre of cheese layer she needs to put on the pizza = 50.27 cm²

4. Radius of photo frame = 9 cm

Circumference of photo frame = 2·π·r = 2 × π × 9 = 56.55 cm

5. Diameter, D of burger Brian made = 5 cm

Area of burger is given by the following relation;

Area of burger = π·D²/4 = π·5²/4 = 19.635 cm².

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

no not all of them.

step-by-step explanation:

some of them have a square base.
