Answer: A. 622 sq. units

Step-by-step explanation:

The surface area of a cylinder is given by :-

S.A.=2\pi r(r+h), where r is the radius , h is height of the cylinder.

Given : The height of the cylinder : h= 2 units

The radius of the cylinder : r= 9 units

Then , the surface area of a cylinder will be :-

S.A.=2(3.14159) 9(9+2)\\\\\Rightarrow\ S.A.=622.03482\approx622\text{sq. units}

Corey invested $1500 when he was a freshman in order to save for college. If he chooses to invest it in an account that earns 3.
Tcecarenko [31]

Answer: He will have $1721.28. after 4 years.

Step-by-step explanation:

The formula we use to find the compounded amount A is :

A=P(1+r)^t, where P= principal value, r = rate of interest , t= time.

As per given , we have

P=$1500  , r=3.5%=0.035 , t= 4 years

Money he will have after 4 years = 1500(1+0.035)^4

=1500(1.035)^4\\\\=1721.28450094\approx1721.28

Hence, he will have $1721.28. after 4 years.

snow_lady [41]

Answer:

546 manogoes

Step-by-step explanation:

Sadie has mangos and watermelons in a ratio of 91:11.

We need to find the number of mangoes if she has 66 watermelons.

It means that,

11x = 66

x = 6

So,

Mangoes = 91x

= 91(6)

= 546

Hence, there are 546 mangoes.
