Answer:

ok this question contains many operations we have addition sign subtraction sign and multiplication sign so in this case we use bodmas and in the bodmas we see multiplication coming fast so the first two letters that have the multiplication sign between them should be multiplied so in this case put a bracket between those two numbers so that you have it like this oneplus (2 x 3)-(4*5) + 6 - 7 plus (8 * 9 )+ 10 so we multiply the numbers in the brackets so that our equation comes to 1 + 6 - 20 + 6 - 7 + 72 + 10 then we rearrange so that you have 1 + 6 plus 6 + 72 + 10 - 20 - 7 1 + 6 + 6 + 72 + 10 is 95 - 20 -7 and your final answer is 68

This right circular cone has a volume of 75π cubic inches. The height of the cone is 9 inches. What is the length of the radius?
sukhopar [10]
\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
V=75\pi \\
h=9
\end{cases}\implies 75\pi =\cfrac{\pi r^2\cdot 9}{3}\implies 75\pi =3\pi r^2
\\\\\\
\cfrac{75\pi }{3\pi }=r^2\implies 25=r^2\implies \sqrt{25}=r\implies 5=r

A company's logo was designed using circles of 3 different. sizes. The diameters of two of the circles are shown. Which measurem
Helga [31]

Answer:

option D . 254.34cm^2

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

The options are:

A . 56.52cm^2

B . 141.30cm^2

C . 1,017.36cm^2

D . 254.34cm^2

step 1

Find the diameter of the largest circle

we know that

The diameter of the largest circle is equal to the sum of the diameter of the two inside circles

so

D=6+12=18\ cm

step 2

Find the area of the largest circle

we know that

The area of the circle is given by the formula

A=\pi r^2

we have

r=18/2=9\ cm ----> the radius is half the diameter

assume

\pi=3.14

substitute

A=(3.14)(9^2)=254.34\ cm^2
