Find the surfacs area of a cone wirh a slant height of 18in and a radius of 7in

Answers

Answer 1

Answer: Formula of the surface area of a cone is:
S.A = Area of base + $(1)/(2)$ × Perimeter of base × height of prism

S.A = $\pi$ r² + $\pi$ rl
= $\pi$ (7)² + $\pi$ (7)(18)
= 49 $\pi$ + 126 $\pi$
= 175 $\pi$ in² (in terms of $\pi$ )
= 549.7787 in²
≈ 550 in²

Amy is 5 years younger than Selina. if Selinas age can be represented by x, write an expression representing Amys age A) 5x
B) 5-x
C) x-5
D) x+5

Answers

Answer:

Option (d) is correct.

Selina's age is written as x + 5

Step-by-step explanation:

Given : Amy is 5 years younger than Selina. if Selina's age can be represented by x,

We have to write an expression representing Amy's age.

Since, x represent the Selina's age.

and also Amy is 5 years younger than Selina

that is Amy is 5 years smaller than Selina

So Selina is 5 year older than Amy

So, Selina's age is written as x + 5

The answer is C) x-5 because you would have to subtract 5 from Selina's height to get to Amy's height.
