Answer:

Let the radius of the cylinder be r and the height be h.

Curved surface area of a cylinder = 2 π r h

Curved surface area of a cylinder = 2 π r h= 2 × 22 / 7 × 7 × 20 = 880 cm^2.

Or of an:

Acute Isosceles Triangle

Side a = 20

Side b = 20

Side c = 14

Angle ∠A = 69.513° = 69°30'46" = 1.21323 rad

Angle ∠B = 69.513° = 69°30'46" = 1.21323 rad

Angle ∠C = 40.975° = 40°58'29" = 0.71514 rad

Area = 131.14496

Perimeter p = 54

Semiperimeter s = 27

Hope this helps! If so please Mark brainliest and rate/heart if it did!

Answer:

1) 6

2)4

3)27

4)126

5)15

Step-by-step explanation:

1. We need to see how many 8-miles are in 24 miles, than multiple it with 2in.

(24/8)*2=3*2=6in

2. Fist we calcue how many 17-feets are in 68feets, and multiple that with 1in.

(68/17)*1=4

3. We first see how many 3ins are in 9ins, and than multiple that with 9feet

(9/3)*9=3*9=27

4. First see how many 2ins are in 36ins, and then multiple it with 7.

(36/2)*7=18*7=126feet

5. See how many 15fts are in 75ft And than multiple it with 3.

(75/15)*3=5*3=15

How do you solve -3(4x+3)+4(6x+1)=43 ?
Anastaziya [24]

Answer:

x = 4

Step-by-step explanation:

Solution:

-3(4x + 3) + 4(6x + 1) = 43

-12x - 9 + 24x + 4 = 43

12x - 5 = 43

12x = 43 + 5

12x = 48

x = 48 / 12

Therefore, x = 4
