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 the newspaper is needed to cover the lateral areas of all five sculptures? (Use 3.14 for Pi and round to the nearest hundredth. Recall the formula L A = pi r l.) 233.15 cm2
466.29 cm2
1,165.73 cm2
2,331.45 cm2

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

what

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
