Answer:

It won't because the area is length times height. So 11 x 11. So some of the car will be hanging out of the garage.

Find the lateral surface area of the figure.
Brut [27]

Surface area of the cylinder = 816.4 sq. ft.

Solution:

Height of the cylinder = 21 ft

Diameter of the cylinder = 10 ft

Radius of the cylinder = 10 ÷ 2 = 5 ft

Use the value of \pi = 3.14

Surface area of the cylinder = 2 \pi r h+2 \pi r^{2}

Substitute the given values in the surface area formula, we get

Surface area of the cylinder $=2\times3.14\times 5\times 21+2 \times3.14\times 5^2

                                               =659.4+157

                                               =816.4 ft²

Hence the surface area of the cylinder is 816.4 sq. ft.

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.
Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is x.

180 = 44 + 90 + x

180 = 134 + x

x= 46

The angle y of the other triangle plus the angle x of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

90 = x + y

90 = 46 + y

y=44

To find ?, we have

180 = 58 + 44 +?

180 = 58 + 44 +?

? =78

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

180 = x + 50 + 25\\180 = x+ 75\\x=105

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

180 = 36 + 105 + y

180 = 141+ y

y=39

?=39
