Answer:
b
Step-by-step explanation:
i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point. So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the
305 to the nearest ten is 310.
Answer:
volume = 13500
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid =
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume =
=
= 13500
volume = 13500
The volume of the pyramid is 13500 .
