Rewrite the fractions as improper fractions:
1. −4 2/5 ÷ (−5)
= -22/5 ÷ −5/1
= -22/5 x -1/5
=22/25
2. −4 4/5÷4
= -24/5 ÷ 4/1
= -24/5 x 1/4
= -6/5
= -1 1/5
3. −2 1/8 ÷ 1 1/4
= -17/8 ÷ 5/4
= -17/8 x 4/5
= -68/40
= -17/10
=-1 7/10
4. −6 7/8 ÷ (−3 3/4)
= -55/8 ÷ -15/4
= -55/8 x -4/15
= 220/40
= 11/6
= 1 5/6
5. −8 3/4÷ 2 1/6
= -35/4 ÷ 13/6
= -35/4 x 6/13
= -210/52
= - 105/26
= -4 1/26

Answer:
The Lateral Surface Area is 911.32 square unit and
Total Surface Area is 1361.7 square unit.
Step-by-step explanation:
For a given Cone
Radius (r) = 12
Height (h) = 21
<u>For Lateral Surface Area</u>
<h3>
<u>Formula</u><u>:</u> </h3>
A = πr√r² + h²
A = 3.14 × 12 × √(12)² + (21)²
A = 3.14 × 12 × √144 + 441
A = 3.14 × 12 × √585
A = 37.68 × 24.18
A = 911.32 square unit
Now,
<u>For</u><u> </u><u>Total</u><u> Surface Area</u>
<h3><u>Formula:</u></h3>
A = πrl + πr²
For Slant height (l)
l² = r² + h²
l² = (12)² + (21)²
l² = 144 + 441
l² = 585
l = 24.18
So,
A = πrl + πr²
A = πr(l + r)
A = 3.14 × 12 × (24.14 + 12)
A = 3.14 × 12 × 36.14
A = 1361.7 square unit
Thus, The <u>Lateral Surface Area</u> is 911.32 square unit and <u>T</u><u>otal Surface Area</u> is 1361.7 square unit.
