The lateral area is expressed as the product of the perimeter of the base and the height. While the surface area is the sum of all areas. The lateral area and the surface area of the box is calculated as follows:
LA = Ph
P = 2l + 2w = (2 x 17) + (2 x 5) = 44 cm
LA = 44 cm x 3.12 cm = 137.28 cm
SA = 2(lw + wh + lh)
SA = 2[(17x5) + (5x3.12) + (17x3.12)]
SA = 307.28 cm
Thus, the lateral area and the surface area are 137 cm and 307 cm, respectively.
3y = 6
Product means multiply so 3 multiplied by y is 3y which is equal to 6. :)
Mammals: If the number of Mammal exhibits is 25 and there are 75 total exhibits, the Mammal exhibits are 1/3 of the total exhibits at this Zoo. The ratio for 1/3 is 1:3, which is 25:75 in most complex form. That's 33.3 as a percentage, or 33.3%.
Reptiles: If the number of Reptile exhibits is 15 and there are 75 total exhibits, the reptile exhibits are 1/5 of the total exhibits here. The ratio for 1/5 is 1:5, which is 15:75 fully written out. This as a percentage is 20%.
I'll message you the other half of the answers.
Answer:
See below.
Step-by-step explanation:
7) 10 x [(7² + 3) - 9]
= 10 x [52 - 9]
= 10 x 43
= 430
9) {[(66 / 11) + 3] x 2}
= [6 + 3] x 2
= 9 x 2
= 18
11) {[(18 - 3) + 3²] - 14} x 3
= {[24] - 14} x 3
= 10 x 3
= 30
Answer I don't know the answer but i can help you find it out, so basically your going to times 3.14 by the numbers in the circle
