Answer:
54π cm²
Step-by-step explanation:
It's pi, or π, but definitely not "pie."
The surface area has two parts: the vertical side and the two ends.
The formula for the area of the vertical sides is A = πr²h, where r is the radius and h is the height. Here, we have:
A = π(3 cm)²(5 cm) = 45π cm²
Each of the ends has the following area: A = πr², or A = 9π cm²
Thus, the total surface area of the cylinder is 45π cm² + 9π cm², or 54π cm²
Answer:
2x-8 = 20-6x
Step-by-step explanation:
The distributive property tells us to multiply the term outside parentheses by everything inside:
2(x-4) = 5(4-2x)+4x
2(x)+2(-4) = 5(4)+5(-2x)+4x
2x-8 = 20-10x+4x
Combining like terms on the right gives us
2x-8 = 20-6x
The numbers you are looking for are -11 and -1.
Answer: 3
Step-by-step explanation:
6/2=3 in 1 hour she can climb 3 miles so if she climbs 9 miles itll only take 3 hours.
Well it has to be either 23 or 9 because you have to add the two smallest sides also you have to subtract them . What are the options ?
