Question

HELP NOW PLEASE !!!Mrs. Havarti's art class made five identical conical sculptures. Each sculpture has a diameter of 9 cm and a slant height of
16.5 cm. The lateral area of each sculpture is to be covered with newspaper. How many square centimeters of newspaper are
needed to cover the lateral areas of all five sculptures? (Use 3.14 for x and round to the nearest hundredth. Recall the formula
LA- rl.)
233.15 cm
466.29 cm
1,165.73 cm
2,331.45 cm

Answer 1

Answer:

1165.73 sq.cm. of newspaper are  needed to cover the lateral areas of all five sculptures

Step-by-step explanation:

Diameter of 1 sculpture = 9 cm

Radius of 1 sculpture =$\frac{9}{2}=4.5 cm$

Slant height of sculpture = l = 16.5 cm

Lateral surface area of each sculpture = $\pi r l = \frac{22}{7} \times 4.5 \times 16.5 =233.3571 cm^2$

Lateral surface area of 5 sculptures =$233.3571 \times 5 =1165.73 cm^2$

Hence 1165.73 sq.cm. of newspaper are  needed to cover the lateral areas of all five sculptures
