X would have to equal 2 because when you multiply that by 7 you get 14 then add 3 and you get 17
Given the surface area of the sphere, for us to obtain the volume we need to get the value of the radius. The surface area of the sphere is given by:
S.A=4πr^2
hence the radius can be calculated as follows;
16=4πr^2
4=πr^2
r=(4/π)^(1/2)
volume of a sphere is given by:
V=4/3πr^3
=4/3*π*(4/π)^(1/2))^3
=32/3 cubic inches
Step-by-step explanation:
it would be B
Answer:
XY = 10 cm
Step-by-step explanation:
XY is a midsegment and is half the length of the 3rd side DE, that is
XY =
DE =
× 20 = 10 cm
