Step-by-step explanation:
diameter (d) = 7cm
radius (r)= d/2 .... formula
= 7/2 .....put the value
= 3.5cm
the measure of radius is 3.5cm.
Answer:
BC = 25
Step-by-step explanation:
To find the length of BC you need to use the pythagorean theorem.
There are two part to a triangle that need to be put into this equation. The hypotenuse(c) and the legs(a, b). The legs would be the side NEXT to the right angle. The hypotenuse is ACROSS from the right angle. In this equation we are looking for the hypotenuse. It doesn't matter which letter the legs replace just remember that the hypotenuse alway has to be C.
Now you have to square the numbers then add.
Now find the square root of 625 to get rid of the squared in the C.
c = 25
Hope this helped.
A =
A =
A ≈ 36.34
The area is approximately
36.34 cm²
Since, you're moving up in exponents, you will move right the number of decimal spaces equivalent to the power of the exponent. Hence, move the decimal point five spaces to the right. There, you now have your answer. :)
