Answer:
both questions answer is 22 this is your answer friend
Answer:
34
Step-by-step explanation:
We know the area is 52 cm and that one length is 13cm. This means that in order to find the missing length, we need to divide 52 by 13. this gives us 4, meaning that the missing side is 4 cm.
Now we add 26 (Double of 13 because it is both sides) to 8 (Double of 4 because they are same lengthening sides)
We then get 34.
Hope this helps :)

You are told the circumference of the sphere. The circumference is the length of the circle around the widest part. You know the formula for the circumference of a circle in terms of radius, so you can find the radius of the sphere.
C = 2πr
496.12 yd = 2*3.14*r
(496.12 yd)/(2*3.14) = r = 79 yd
Then the surface area of a sphere is given by ...
A = 4πr^2
A = 4*3.14*(79 yd)²
A = 78,386.96 yd²
_____
You can also find the area of a sphere in terms of its circumference.
A = C²/π
A = (496.12 yd)²/3.14 = 78,386.96 yd² . . . . same as above.
(The surface area in your problem statement, 3117.25 yd², corresponds to a sphere with a circumference of about 98.94 yd. The circumference given in the problem statement is almost 5 times that, which is why the area is almost 5²=25 times the area in your problem statement. This is a good one to ask your teacher about.)
Answer:
2
Step-by-step explanation:
The running track is 3/4 mile long
The track and field team ran 2 2/3 laps around the track
Therefore the number of miles ran by the team can be calculated as follows
°= 2 2/3 × 3/4
= 8/3 × 3/4
= 2
Hence the team ran 2 miles
