The sector of a circle with a 12-inch radius has a central angle measure of 60°.

oksian1 [2.3K]

Answer: Area of sector in term of π is 24 in.².

Step-by-step explanation:

Since we have given that

Radius of the sector of a circle = 12 inch

Central angle = 60°

As we know the formula for "Area of sector":

$Area=\frac{\theta}{360^\circ}\pi r^2\\\\Area=\frac{60}{360}\times \pi\times 12\times 12\\\\Area=24\pi\ inch^2$

Hence, Area of sector in term of π is 24 in.².

Sammie read at the rate of 25 pages per hour. Alex read at the rate of 1/2 of a pages per minute. Who was reading faster? By how

exis [7]

Answer:

Alex is reading faster by 5 more pages per hour.

Step-by-step explanation:

Alex's rate of reading is 1/2 pages per minute, or 1 page every 2 minutes. To convert his rate to pages per hour, we can divide 60 (minutes in an hour) by 2 (minutes it takes Alex to read a page) which is equal to 30 (pages read in an hour). Therefore, Alex is reading at 30 pages an hour and reading 5 more pages an hour than Sammie.

Answer ASAP Find the area

slavikrds [6]

In this problem, you are asked to find the area of the trapezoid. The formula in finding the area of the trapezoid is:

A = [(a + b)/2] x h

Where a = base 1

b = base 2

h = height

Substituting the given measurements to the formula:

A = [(1.7 m + 6.7 m) / 2] x 5 m

A = (8.4 m / 2) x 5 m
