Find the area of the circle to the nearest whole number, if necessary!

Mathematics
1 answer:
astra-53 [7]2 years ago
5 0

Answer:

The circle has an area of about 1385 square mm.

Step-by-step explanation:

Let's recall that circles have an area that can be found with the following formula:

A=\pi r^{2}

where r is the radius of the circle.

Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.

A=\pi (21)^2\\A=441\pi \\A=1385.44236...

So, to the nearest whole number, the area of the circle is 1385 square mm.

6/5y-10=-4

move -10 to the other side

sign changes from -10 to 10

6/5y-10+10= -4+10

6/5y= 6

Mutiply by 5/6 for both sides

6/5(5/6)y=6(5/6)

4. A credit card company applies a 6% fee on all transactions under $10. You purchased coffee for $4.80. What fee amount will be
Akimi4 [234]

Answer:

The fee amount applied to my bill will be $0.288 or 28.8 cents.

Step-by-step explanation:

The coffee cost under $10; therefore, a 6% fee will be applied.

6% of $4.8 is

\dfrac{6\%}{100\%}  * \$ 4.80

0.06*\$4.80 = \$0.288.

Thus, the fee amount applied to my bill will be $0.288 or 28.8 cents.
