need help with one more. Find the following measure for this figure.

OpenStudy (anonymous):

what is the Lateral area?

OpenStudy (anonymous):

OpenStudy (anonymous):

a.55pi square units b.5√(47)pi square units c.5√(146)pi square units

OpenStudy (anonymous):

Do pythagorean theorem (a^2+b^2 = c^2) with a=5 and b=11 to get the slant height. Than the formula for lateral area is Pi*radius*slant height

OpenStudy (anonymous):

so the slant hight is 146?

OpenStudy (anonymous):

square root of 146

OpenStudy (anonymous):

\[\sqrt{146}\]

OpenStudy (anonymous):

so the answer is C right

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

can you help me with one more what is the Volume of the same figure?

OpenStudy (anonymous):

options: a.275pi cubic units b.91 2/3pi cubic units c.36 2/3pi cubic units

OpenStudy (anonymous):

1/3*pi*r^2*h

OpenStudy (anonymous):

Don't use slant height though use the height that they gave you for h

OpenStudy (anonymous):

1/3*pi*5^2*11 is this right?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

so the answer would be A.275cubic units. right?

OpenStudy (anonymous):

yea
