Answer:
v=lxbxh
v=5x5x5
v=125cm
volume b
v=lxbxh
v=5x5x5
v=125cm
volume A+volume B
125+125=150
Step-by-step explanation:
you find the first one first then you find the second one then you add
-- PQS is a right triangle, because a tangent to a circle is
perpendicular to the radius at the point of tangency.
-- You know PQ (a leg) and PS (the hypotenuse) so you can
find the length of the other leg.
QS = (PQ)² - (PS)² = (4.2)² - (8.2)² = <u>7.043</u>.
-- If you draw the radius PR, then you have another right triangle
back to back with the first one. Each hypotenuse is a radius, so
those are equal, and PQ is common to both triangles.
So RQ is equal to QS.
-- The length of the whole chord RS is double the length of QS .
RS = 2 x (QS) = 2 x (7.043) = <em>14.085</em> .
That looks a lot like the third choice down.
A revolution is once around the outside measure of the tire. This is also known as the circumference of a circle. The circumference of this tire is found in the formula
where r is the radius of the tire and pi is given as the fraction equivalent 22/7. If we fill in the formula accordingly, we have
and the circumference is . This means for us that the tire travels a total of 88/7 feet in 1 revolution. If the tire travels 8,800 feet in one minute, we need to find out how moany revolutions this is equal to. We find this out by dividing 8,800 by 88/7. Doing this looks like this:
.
Remember that when we divide fractions, we bring up the bottom fraction and flip it to multiply. That means that the tire makes 700 revolutions in 1 minute. In 3 minutes it makes 700 times 3 which is 2100 revolutions.
Number of times pencils are more than rubbers = 7 ÷ 2 = 3.5 times
Answer: 3.5 times
