Answer:

Step-by-step explanation:

Each circle is pi*r*r (pi r squared)

So 2*pi*r*r

The top of the rectangle if just the circumference of the circle = 2*pi*r

So the area of the rectangle is 2*pi*r*h

So the total area =2*pi*r*r+2*pi*r*h

PLEASE HELP ASAP!!!! 100% CORRECT ANSWERS ONLY PLEASE!!!!

Area= 2πr

So,

If you were to multiply the radius by 2 since 2 is not in the equations,

4*2= 8

8π ft^2 would be the correct answer.

I hope this helps!

The area of a square is (4x + 3)^2 square inches. The perimeter of the square is 172 inches. What is the value of x?

stepan [7]

Answer:

x = 10

Step-by-step explanation:

the area of a square = s² ( s is the side length )

s² = (4x + 3)² ( take the square root of both sides )

s = $\sqrt{(4x+3)^2}$ = 4x + 3

perimeter = 4s = 172, that is

4(4x + 3) = 172 ( distribute left side )

16x + 12 = 172 ( subtract 12 from both sides )

16x = 160 ( divide both sides by 16 )

x = 10

Answer:

1.9

Step-by-step explanation:

Use triginometry to find the side length. So cosθ= $\frac{?}{2}$ . Rearrange the equation so it looks like 2cosθ=?. We are given θ (20 degrees) so 2cos(20degrees)=?.

ANSWER

B. 81

EXPLANATION

The given expression is:

${3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} }$

Recall that:

${a}^{m} \div {a}^{n} = {a}^{m - n}$

We simplify the expression using the properties of exponents to obtain:

${3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{ \frac{11}{5} - - \frac{9}{5} }$

We simplify the exponents to get;

${3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{ \frac{11 + 9}{5}}$

${3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{ \frac{20}{5}}$

${3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{4}$

${3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = 81$

The correct answer is B. 81
