Answer:

the \: third \: angle \: of \: triangle \: is \: 70 \\sum \: of \: triangle \: angles = 180 \:   \\ 70 + 5x + 6x - 11 = 180 \\ 11x + 59 = 180 \\ 11x = 180 - 59 = 121 \\ x = 121 \div 11 = 11

Answer:

Surface Area is 56π cm²

Step-by-step explanation:

The area for a cylinder's surface area is

a=2πrh+2πr²

The cylinder base's radius is 4 cm

The cylinder's height is 3 cm

Putting into the equation:

a=2×π×4×3+2×π×4²

a=2π×4×3+2×π×4²

a=8π×3+2×π×4²

a=24π+2×π×4²

a=24π+2×π×16

a=24π+2π×16

a=24π+32π

a=56π

The surface area of the cylinder is 56π cm².

Explain how you could mentally find 8 x 45 by using the distributive property
dangina [55]
First, break up 45 into 40 and 5 then multipy 8(40) which equals 320 and multipy 8(5) which equals 40. Thrn add 320+40 to get the product 360.
Hope this helped

8x45
8(40)+8(5)

A bicycle wheel makes five rotations. the bicycle travels 44.48 ft. Find the diameter of the wheel in inches.
Tema [17]

Answer:

2.42 feet

Step-by-step explanation:

the bicycle wheel rotates 5 times and travels 37.94 feet, then we know that the circumference of the wheel (the outside of the wheel as it touches the ground 5 times around) is 37.94/5 = 7.588

 

Then we use the formula for the circumference of a circle: 2(pi)(radius) = circumference

 

We plug in what we know 2(3.14)(radius) = 7.588 and then solve for the radius

 

We divide 2 from both sides of the equation (3.14)(radius) = 3.794

 

We divide pi from both sides (radius) = 1.208

 

Then the last step, we multiply the radius by 2, because we need the diameter, which is double the radius

 

1.208 * 2 = 2.416 or 2.42 rounded up

 

Final answer = 2.42 feet
