Answer:

439.6 cm²

Step-by-step explanation:

Surface area of the cylinder is the length of the rectangular strip that goes around, and the are of the two circles

Area circle = πr²

Area circle = 3.14 * 7²

Area circle = 3.14 * 49

Area circle = 153.86

The area of both circles is 153.86 x 2 = 307.72

The rectangular strip is the diameter by the height

Diameter = 2πr

Diameter = 14*3.14 = 43.96

The strip is 43.96 x 3 = 131.88

Total surface area is 307.72 + 131.88 = 439.6

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

In what career would you most likely apply concepts from geometry?
Nitella [24]

Answer:

- Architect

- Cartographer and Photogrammetrist

- Drafter

- Mechanical Engineer

- Surveyor

- Urban and Regional Planner

Step-by-step explanation:

Architects utilize geometric principles while designing layouts for their ongoing projects, which can include buildings, electrical systems, and plumbing architecture.

Cartographers utilize geographic data to create or update maps for use in education, as well as environmental presentations.

Using the same geometric knowledge and applications as architects and engineers, drafters create design plans with the use of computer-aided design (CAD) software.

Mechanical engineers, some of the most diversified engineers, use a multitude of geometric concepts to design mechanical devices, or update existing structures.

Surveyors use geometry to take exact measurements of boundaries for different types of property.

Urban and regional planners rely on the same geometry practices used by surveyors when examining the positives and negatives of introducing new and updated plans for a community.

Answer:

y=29

Step-by-step explanation:

Since the angles are across a vertex from one another, they are congruent and equal. You can also see this by reflecting  or folding it in half through the vertex. They will be the same. This means we can write the following equation and solve using inverse operations:

4y-8=79+y

4y-y-8=79+y-y

3y-8=79

3y-8+8=79+8

3y=87

y=29

Write a linear function of f with f(-3)=-2 and f(-2)=3
katrin2010 [14]

Answer:

y=5x+13

Step-by-step explanation:

when x=-3, y=-2, and when x=-2,  y=3. we know that every time x increases by 1, y also increases by 5. This means that the slope is 5. to find the y-intercept, we need x to be 0. to find that, increase x by 2. if x increases by 2, then y would also increase by 10. add 10 to 3 and add 2 to -2 to get x=0 and y=13. the coordinates would be (0,13). the y-intercept is 13. now that we have enough information, we can conclude that y=5x+13. To check your answer, plug in the values for x.
